+1.7 What is memory spread ?
+---------------------------
+There are two boolean flag files per cpuset that control where the
+kernel allocates pages for the file system buffers and related in
+kernel data structures.  They are called 'memory_spread_page' and
+'memory_spread_slab'.
+
+If the per-cpuset boolean flag file 'memory_spread_page' is set, then
+the kernel will spread the file system buffers (page cache) evenly
+over all the nodes that the faulting task is allowed to use, instead
+of preferring to put those pages on the node where the task is running.
+
+If the per-cpuset boolean flag file 'memory_spread_slab' is set,
+then the kernel will spread some file system related slab caches,
+such as for inodes and dentries evenly over all the nodes that the
+faulting task is allowed to use, instead of preferring to put those
+pages on the node where the task is running.
+
+The setting of these flags does not affect anonymous data segment or
+stack segment pages of a task.
+
+By default, both kinds of memory spreading are off, and memory
+pages are allocated on the node local to where the task is running,
+except perhaps as modified by the tasks NUMA mempolicy or cpuset
+configuration, so long as sufficient free memory pages are available.
+
+When new cpusets are created, they inherit the memory spread settings
+of their parent.
+
+Setting memory spreading causes allocations for the affected page
+or slab caches to ignore the tasks NUMA mempolicy and be spread
+instead.    Tasks using mbind() or set_mempolicy() calls to set NUMA
+mempolicies will not notice any change in these calls as a result of
+their containing tasks memory spread settings.  If memory spreading
+is turned off, then the currently specified NUMA mempolicy once again
+applies to memory page allocations.
+
+Both 'memory_spread_page' and 'memory_spread_slab' are boolean flag
+files.  By default they contain "0", meaning that the feature is off
+for that cpuset.  If a "1" is written to that file, then that turns
+the named feature on.
+
+The implementation is simple.
+
+Setting the flag 'memory_spread_page' turns on a per-process flag
+PF_SPREAD_PAGE for each task that is in that cpuset or subsequently
+joins that cpuset.  The page allocation calls for the page cache
+is modified to perform an inline check for this PF_SPREAD_PAGE task
+flag, and if set, a call to a new routine cpuset_mem_spread_node()
+returns the node to prefer for the allocation.
+
+Similarly, setting 'memory_spread_cache' turns on the flag
+PF_SPREAD_SLAB, and appropriately marked slab caches will allocate
+pages from the node returned by cpuset_mem_spread_node().
+
+The cpuset_mem_spread_node() routine is also simple.  It uses the
+value of a per-task rotor cpuset_mem_spread_rotor to select the next
+node in the current tasks mems_allowed to prefer for the allocation.
+
+This memory placement policy is also known (in other contexts) as
+round-robin or interleave.
+
+This policy can provide substantial improvements for jobs that need
+to place thread local data on the corresponding node, but that need
+to access large file system data sets that need to be spread across
+the several nodes in the jobs cpuset in order to fit.  Without this
+policy, especially for jobs that might have one thread reading in the
+data set, the memory allocation across the nodes in the jobs cpuset
+can become very uneven.

 The Address Space Object
 ========================
 
-The address space object is used to identify pages in the page cache.
-
+The address space object is used to group and manage pages in the page
+cache.  It can be used to keep track of the pages in a file (or
+anything else) and also track the mapping of sections of the file into
+process address spaces.
+
+There are a number of distinct yet related services that an
+address-space can provide.  These include communicating memory
+pressure, page lookup by address, and keeping track of pages tagged as
+Dirty or Writeback.
+
+The first can be used independently to the others.  The VM can try to
+either write dirty pages in order to clean them, or release clean
+pages in order to reuse them.  To do this it can call the ->writepage
+method on dirty pages, and ->releasepage on clean pages with
+PagePrivate set. Clean pages without PagePrivate and with no external
+references will be released without notice being given to the
+address_space.
+
+To achieve this functionality, pages need to be placed on an LRU with
+lru_cache_add and mark_page_active needs to be called whenever the
+page is used.
+
+Pages are normally kept in a radix tree index by ->index. This tree
+maintains information about the PG_Dirty and PG_Writeback status of
+each page, so that pages with either of these flags can be found
+quickly.
+
+The Dirty tag is primarily used by mpage_writepages - the default
+->writepages method.  It uses the tag to find dirty pages to call
+->writepage on.  If mpage_writepages is not used (i.e. the address
+provides its own ->writepages) , the PAGECACHE_TAG_DIRTY tag is
+almost unused.  write_inode_now and sync_inode do use it (through
+__sync_single_inode) to check if ->writepages has been successful in
+writing out the whole address_space.
+
+The Writeback tag is used by filemap*wait* and sync_page* functions,
+via wait_on_page_writeback_range, to wait for all writeback to
+complete.  While waiting ->sync_page (if defined) will be called on
+each page that is found to require writeback.
+
+An address_space handler may attach extra information to a page,
+typically using the 'private' field in the 'struct page'.  If such
+information is attached, the PG_Private flag should be set.  This will
+cause various VM routines to make extra calls into the address_space
+handler to deal with that data.
+
+An address space acts as an intermediate between storage and
+application.  Data is read into the address space a whole page at a
+time, and provided to the application either by copying of the page,
+or by memory-mapping the page.
+Data is written into the address space by the application, and then
+written-back to storage typically in whole pages, however the
+address_space has finer control of write sizes.
+
+The read process essentially only requires 'readpage'.  The write
+process is more complicated and uses prepare_write/commit_write or
+set_page_dirty to write data into the address_space, and writepage,
+sync_page, and writepages to writeback data to storage.
+
+Adding and removing pages to/from an address_space is protected by the
+inode's i_mutex.
+
+When data is written to a page, the PG_Dirty flag should be set.  It
+typically remains set until writepage asks for it to be written.  This
+should clear PG_Dirty and set PG_Writeback.  It can be actually
+written at any point after PG_Dirty is clear.  Once it is known to be
+safe, PG_Writeback is cleared.
+
+Writeback makes use of a writeback_control structure...

+      The PG_Dirty flag has been cleared and PageLocked is true.
+      writepage should start writeout, should set PG_Writeback,
+      and should make sure the page is unlocked, either synchronously
+      or asynchronously when the write operation completes.
+
+      If wbc->sync_mode is WB_SYNC_NONE, ->writepage doesn't have to
+      try too hard if there are problems, and may choose to write out
+      other pages from the mapping if that is easier (e.g. due to
+      internal dependencies).  If it chooses not to start writeout, it
+      should return AOP_WRITEPAGE_ACTIVATE so that the VM will not keep
+      calling ->writepage on that page.
+
+      See the file "Locking" for more details.
 
   readpage: called by the VM to read a page from backing store.
+       The page will be Locked when readpage is called, and should be
+       unlocked and marked uptodate once the read completes.
+       If ->readpage discovers that it needs to unlock the page for
+       some reason, it can do so, and then return AOP_TRUNCATED_PAGE.
+       In this case, the page will be relocated, relocked and if
+       that all succeeds, ->readpage will be called again.
 
   sync_page: called by the VM to notify the backing store to perform all
   	queued I/O operations for a page. I/O operations for other pages
 	associated with this address_space object may also be performed.
 
+	This function is optional and is called only for pages with
+  	PG_Writeback set while waiting for the writeback to complete.

   writepages: called by the VM to write out pages associated with the

+  	the writeback_control will specify a range of pages that must be

+	and that many pages should be written if possible.
+	If no ->writepages is given, then mpage_writepages is used
+  	instead.  This will choose pages from the address space that are
+  	tagged as DIRTY and will pass them to ->writepage.
 
   set_page_dirty: called by the VM to set a page dirty.
+        This is particularly needed if an address space attaches
+        private data to a page, and that data needs to be updated when
+        a page is dirtied.  This is called, for example, when a memory
+	mapped page gets modified.
+	If defined, it should set the PageDirty flag, and the
+        PAGECACHE_TAG_DIRTY tag in the radix tree.

+  	object. This is essentially just a vector version of
+  	readpage.  Instead of just one page, several pages are
+  	requested.
+	readpages is only used for read-ahead, so read errors are
+  	ignored.  If anything goes wrong, feel free to give up.
 
   prepare_write: called by the generic write path in VM to set up a write

-  commit_write: called by the generic write path in VM to write page to

+  	request for a page.  This indicates to the address space that
+  	the given range of bytes is about to be written.  The
+  	address_space should check that the write will be able to
+  	complete, by allocating space if necessary and doing any other
+  	internal housekeeping.  If the write will update parts of
+  	any basic-blocks on storage, then those blocks should be
+  	pre-read (if they haven't been read already) so that the
+  	updated blocks can be written out properly.
+	The page will be locked.  If prepare_write wants to unlock the
+  	page it, like readpage, may do so and return
+  	AOP_TRUNCATED_PAGE.
+	In this case the prepare_write will be retried one the lock is
+  	regained.
+
+  commit_write: If prepare_write succeeds, new data will be copied
+        into the page and then commit_write will be called.  It will
+        typically update the size of the file (if appropriate) and
+        mark the inode as dirty, and do any other related housekeeping

   bmap: called by the VFS to map a logical block offset within object to
-  	physical block number. This method is use by for the legacy FIBMAP
-	ioctl. Other uses are discouraged.
-
-  invalidatepage: called by the VM on truncate to disassociate a page from its
-  	address_space mapping.
-
-  releasepage: called by the VFS to release filesystem specific metadata from

-
-  direct_IO: called by the VM for direct I/O writes and reads.
+  	physical block number. This method is used by the FIBMAP
+  	ioctl and for working with swap-files.  To be able to swap to
+  	a file, the file must have a stable mapping to a block
+  	device.  The swap system does not go through the filesystem
+  	but instead uses bmap to find out where the blocks in the file
+  	are and uses those addresses directly.
+
+
+  invalidatepage: If a page has PagePrivate set, then invalidatepage
+        will be called when part or all of the page is to be removed
+	from the address space.  This generally corresponds to either a
+	truncation or a complete invalidation of the address space
+	(in the latter case 'offset' will always be 0).
+	Any private data associated with the page should be updated
+	to reflect this truncation.  If offset is 0, then
+	the private data should be released, because the page
+	must be able to be completely discarded.  This may be done by
+        calling the ->releasepage function, but in this case the
+        release MUST succeed.
+
+  releasepage: releasepage is called on PagePrivate pages to indicate
+        that the page should be freed if possible.  ->releasepage
+        should remove any private data from the page and clear the
+        PagePrivate flag.  It may also remove the page from the
+        address_space.  If this fails for some reason, it may indicate
+        failure with a 0 return value.
+	This is used in two distinct though related cases.  The first
+        is when the VM finds a clean page with no active users and
+        wants to make it a free page.  If ->releasepage succeeds, the
+        page will be removed from the address_space and become free.
+
+	The second case if when a request has been made to invalidate
+        some or all pages in an address_space.  This can happen
+        through the fadvice(POSIX_FADV_DONTNEED) system call or by the
+        filesystem explicitly requesting it as nfs and 9fs do (when
+        they believe the cache may be out of date with storage) by
+        calling invalidate_inode_pages2().
+	If the filesystem makes such a call, and needs to be certain
+        that all pages are invalidated, then its releasepage will
+        need to ensure this.  Possibly it can clear the PageUptodate
+        bit if it cannot free private data yet.
+
+  direct_IO: called by the generic read/write routines to perform
+        direct_IO - that is IO requests which bypass the page cache
+        and transfer data directly between the storage and the
+        application's address space.
 
   get_xip_page: called by the VM to translate a block number to a page.
 	The page is valid until the corresponding filesystem is unmounted.
 	Filesystems that want to use execute-in-place (XIP) need to implement
 	it.  An example implementation can be found in fs/ext2/xip.c.
 
+  migrate_page:  This is used to compact the physical memory usage.
+        If the VM wants to relocate a page (maybe off a memory card
+        that is signalling imminent failure) it will pass a new page
+	and an old page to this function.  migrate_page should
+	transfer any private data across and update any references
+        that it has to the page.

+--- 7.1 Symbols fron the kernel (vmlinux + modules)
+
+	During a kernel build a file named Module.symvers will be generated.
+	Module.symvers contains all exported symbols from the kernel and
+	compiled modules. For each symbols the corresponding CRC value
+	is stored too.
+
+	The syntax of the Module.symvers file is:
+		<CRC>       <Symbol>           <module>
+	Sample:
+		0x2d036834  scsi_remove_host   drivers/scsi/scsi_mod
 
+	For a kernel build without CONFIG_MODVERSIONING enabled the crc
+	would read: 0x00000000
+
+	Module.symvers serve two purposes.
+	1) It list all exported symbols both from vmlinux and all modules
+	2) It list CRC if CONFIG_MODVERSION is enabled
+
+--- 7.2 Symbols and external modules
+
+	When building an external module the build system needs access to
+	the symbols from the kernel to check if all external symbols are
+	defined. This is done in the MODPOST step and to obtain all
+	symbols modpost reads Module.symvers from the kernel.
+	If a Module.symvers file is present in the directory where
+	the external module is being build this file will be read too.
+	During the MODPOST step a new Module.symvers file will be written
+	containing all exported symbols that was not defined in the kernel.
+	
+--- 7.3 Symbols from another external module
+
+	Sometimes one external module uses exported symbols from another
+	external module. Kbuild needs to have full knowledge on all symbols
+	to avoid spitting out warnings about undefined symbols.
+	Two solutions exist to let kbuild know all symbols of more than
+	one external module.
+	The method with a top-level kbuild file is recommended but may be
+	impractical in certain situations.
+
+	Use a top-level Kbuild file
+		If you have two modules: 'foo', 'bar' and 'foo' needs symbols
+		from 'bar' then one can use a common top-level kbuild file so
+		both modules are compiled in same build.
+
+		Consider following directory layout:
+		./foo/ <= contains the foo module
+		./bar/ <= contains the bar module
+		The top-level Kbuild file would then look like:
+		
+		#./Kbuild: (this file may also be named Makefile)
+			obj-y := foo/ bar/
+
+		Executing:
+			make -C $KDIR M=`pwd`
+
+		will then do the expected and compile both modules with full
+		knowledge on symbols from both modules.
+
+	Use an extra Module.symvers file
+		When an external module is build a Module.symvers file is
+		generated containing all exported symbols which are not
+		defined in the kernel.
+		To get access to symbols from module 'bar' one can copy the
+		Module.symvers file from the compilation of the 'bar' module
+		to the directory where the 'foo' module is build.
+		During the module build kbuild will read the Module.symvers
+		file in the directory of the external module and when the
+		build is finished a new Module.symvers file is created
+		containing the sum of all symbols defined and not part of the
+		kernel.

+Documentation for userland software suspend interface
+	(C) 2006 Rafael J. Wysocki <rjw@sisk.pl>
+
+First, the warnings at the beginning of swsusp.txt still apply.
+
+Second, you should read the FAQ in swsusp.txt _now_ if you have not
+done it already.
+
+Now, to use the userland interface for software suspend you need special
+utilities that will read/write the system memory snapshot from/to the
+kernel.  Such utilities are available, for example, from
+<http://www.sisk.pl/kernel/utilities/suspend>.  You may want to have
+a look at them if you are going to develop your own suspend/resume
+utilities.
+
+The interface consists of a character device providing the open(),
+release(), read(), and write() operations as well as several ioctl()
+commands defined in kernel/power/power.h.  The major and minor
+numbers of the device are, respectively, 10 and 231, and they can
+be read from /sys/class/misc/snapshot/dev.
+
+The device can be open either for reading or for writing.  If open for
+reading, it is considered to be in the suspend mode.  Otherwise it is
+assumed to be in the resume mode.  The device cannot be open for reading
+and writing.  It is also impossible to have the device open more than once
+at a time.
+
+The ioctl() commands recognized by the device are:
+
+SNAPSHOT_FREEZE - freeze user space processes (the current process is
+	not frozen); this is required for SNAPSHOT_ATOMIC_SNAPSHOT
+	and SNAPSHOT_ATOMIC_RESTORE to succeed
+
+SNAPSHOT_UNFREEZE - thaw user space processes frozen by SNAPSHOT_FREEZE
+
+SNAPSHOT_ATOMIC_SNAPSHOT - create a snapshot of the system memory; the
+	last argument of ioctl() should be a pointer to an int variable,
+	the value of which will indicate whether the call returned after
+	creating the snapshot (1) or after restoring the system memory state
+	from it (0) (after resume the system finds itself finishing the
+	SNAPSHOT_ATOMIC_SNAPSHOT ioctl() again); after the snapshot
+	has been created the read() operation can be used to transfer
+	it out of the kernel
+
+SNAPSHOT_ATOMIC_RESTORE - restore the system memory state from the
+	uploaded snapshot image; before calling it you should transfer
+	the system memory snapshot back to the kernel using the write()
+	operation; this call will not succeed if the snapshot
+	image is not available to the kernel
+
+SNAPSHOT_FREE - free memory allocated for the snapshot image
+
+SNAPSHOT_SET_IMAGE_SIZE - set the preferred maximum size of the image
+	(the kernel will do its best to ensure the image size will not exceed
+	this number, but if it turns out to be impossible, the kernel will
+	create the smallest image possible)
+
+SNAPSHOT_AVAIL_SWAP - return the amount of available swap in bytes (the last
+	argument should be a pointer to an unsigned int variable that will
+	contain the result if the call is successful).
+
+SNAPSHOT_GET_SWAP_PAGE - allocate a swap page from the resume partition
+	(the last argument should be a pointer to a loff_t variable that
+	will contain the swap page offset if the call is successful)
+
+SNAPSHOT_FREE_SWAP_PAGES - free all swap pages allocated with
+	SNAPSHOT_GET_SWAP_PAGE
+
+SNAPSHOT_SET_SWAP_FILE - set the resume partition (the last ioctl() argument
+	should specify the device's major and minor numbers in the old
+	two-byte format, as returned by the stat() function in the .st_rdev
+	member of the stat structure); it is recommended to always use this
+	call, because the code to set the resume partition could be removed from
+	future kernels
+
+The device's read() operation can be used to transfer the snapshot image from
+the kernel.  It has the following limitations:
+- you cannot read() more than one virtual memory page at a time
+- read()s accross page boundaries are impossible (ie. if ypu read() 1/2 of
+	a page in the previous call, you will only be able to read()
+	_at_ _most_ 1/2 of the page in the next call)
+
+The device's write() operation is used for uploading the system memory snapshot
+into the kernel.  It has the same limitations as the read() operation.
+
+The release() operation frees all memory allocated for the snapshot image
+and all swap pages allocated with SNAPSHOT_GET_SWAP_PAGE (if any).
+Thus it is not necessary to use either SNAPSHOT_FREE or
+SNAPSHOT_FREE_SWAP_PAGES before closing the device (in fact it will also
+unfreeze user space processes frozen by SNAPSHOT_UNFREEZE if they are
+still frozen when the device is being closed).
+
+Currently it is assumed that the userland utilities reading/writing the
+snapshot image from/to the kernel will use a swap parition, called the resume
+partition, as storage space.  However, this is not really required, as they
+can use, for example, a special (blank) suspend partition or a file on a partition
+that is unmounted before SNAPSHOT_ATOMIC_SNAPSHOT and mounted afterwards.
+
+These utilities SHOULD NOT make any assumptions regarding the ordering of
+data within the snapshot image, except for the image header that MAY be
+assumed to start with an swsusp_info structure, as specified in
+kernel/power/power.h.  This structure MAY be used by the userland utilities
+to obtain some information about the snapshot image, such as the size
+of the snapshot image, including the metadata and the header itself,
+contained in the .size member of swsusp_info.
+
+The snapshot image MUST be written to the kernel unaltered (ie. all of the image
+data, metadata and header MUST be written in _exactly_ the same amount, form
+and order in which they have been read).  Otherwise, the behavior of the
+resumed system may be totally unpredictable.
+
+While executing SNAPSHOT_ATOMIC_RESTORE the kernel checks if the
+structure of the snapshot image is consistent with the information stored

+in accordance with it:
+1. 	If the value is 1 (ie. the system memory snapshot has just been
+	created and the system is ready for saving it):
+	(a)	The suspending utility MUST NOT close the snapshot device
+		_unless_ the whole suspend procedure is to be cancelled, in
+		which case, if the snapshot image has already been saved, the
+		suspending utility SHOULD destroy it, preferrably by zapping
+		its header.  If the suspend is not to be cancelled, the
+		system MUST be powered off or rebooted after the snapshot
+		image has been saved.
+	(b)	The suspending utility SHOULD NOT attempt to perform any
+		file system operations (including reads) on the file systems
+		that were mounted before SNAPSHOT_ATOMIC_SNAPSHOT has been
+		called.  However, it MAY mount a file system that was not
+		mounted at that time and perform some operations on it (eg.
+		use it for saving the image).
+2.	If the value is 0 (ie. the system state has just been restored from
+	the snapshot image), the suspending utility MUST close the snapshot
+	device.  Afterwards it will be treated as a regular userland process,
+	so it need not exit.
+
+The resuming utility SHOULD NOT attempt to mount any file systems that could
+be mounted before suspend and SHOULD NOT attempt to perform any operations
+involving such file systems.

 problem for S1 standby, because hardware should retain its state over
 that.
 
+We either have to run video BIOS during early resume, or interpret it
+using vbetool later, or maybe nothing is neccessary on particular
+system because video state is preserved. Unfortunately different
+methods work on different systems, and no known method suits all of
+them.
+
+Userland application called s2ram has been developed; it contains long
+whitelist of systems, and automatically selects working method for a
+given system. It can be downloaded from CVS at
+www.sf.net/projects/suspend . If you get a system that is not in the
+whitelist, please try to find a working solution, and submit whitelist
+entry so that work does not need to be repeated.

+Currently, VBE_SAVE method (6 below) works on most
+systems. Unfortunately, vbetool only runs after userland is resumed,
+so it makes debugging of early resume problems
+hard/impossible. Methods that do not rely on userland are preferable.

+one (DS2482-100) or eight (DS2482-800) 1-wire busses.
+
+
+General Remarks
+---------------
+
+Valid addresses are 0x18, 0x19, 0x1a, and 0x1b.
+However, the device cannot be detected without writing to the i2c bus, so no
+detection is done.
+You should force the device address.
+
+$ modprobe ds2482 force=0,0x18

+ * SECTION: the internal buffer
+ */
+
+/*
+ * The internal buffer is meant to store obaque blobs of data, so it does
+ * not know of higher level concepts like triggers.
+ * It consists of a number of pages that are used as a ringbuffer. Each data
+ * blob is stored in a simple record that consists of an integer, which
+ * contains the size of the following data, and the data bytes themselfes.
+ *
+ * To allow for multiple independent readers we create one internal buffer
+ * each time the device is opened and destroy the buffer when the file is
+ * closed again. The number of pages used for this buffer is determined by
+ * the module parmeter eer_pages.
+ *
+ * One record can be written to a buffer by using the functions
+ * - dasd_eer_start_record (one time per record to write the size to the
+ *                          buffer and reserve the space for the data)
+ * - dasd_eer_write_buffer (one or more times per record to write the data)
+ * The data can be written in several steps but you will have to compute
+ * the total size up front for the invocation of dasd_eer_start_record.
+ * If the ringbuffer is full, dasd_eer_start_record will remove the required
+ * number of old records.
+ *
+ * A record is typically read in two steps, first read the integer that
+ * specifies the size of the following data, then read the data.
+ * Both can be done by
+ * - dasd_eer_read_buffer
+ *
+ * For all mentioned functions you need to get the bufferlock first and keep
+ * it until a complete record is written or read.
+ *
+ * All information necessary to keep track of an internal buffer is kept in
+ * a struct eerbuffer. The buffer specific to a file pointer is strored in
+ * the private_data field of that file. To be able to write data to all
+ * existing buffers, each buffer is also added to the bufferlist.
+ * If the user does not want to read a complete record in one go, we have to
+ * keep track of the rest of the record. residual stores the number of bytes
+ * that are still to deliver. If the rest of the record is invalidated between
+ * two reads then residual will be set to -1 so that the next read will fail.
+ * All entries in the eerbuffer structure are protected with the bufferlock.
+ * To avoid races between writing to a buffer on the one side and creating
+ * and destroying buffers on the other side, the bufferlock must also be used
+ * to protect the bufferlist.

+ * SECTION: The extended error reporting functionality
+ */
+
+/*
+ * When a DASD device driver wants to report an error, it calls the
+ * function dasd_eer_write and gives the respective trigger ID as
+ * parameter. Currently there are four kinds of triggers:
+ *
+ * DASD_EER_FATALERROR:  all kinds of unrecoverable I/O problems
+ * DASD_EER_PPRCSUSPEND: PPRC was suspended
+ * DASD_EER_NOPATH:      There is no path to the device left.
+ * DASD_EER_STATECHANGE: The state of the device has changed.
+ *
+ * For the first three triggers all required information can be supplied by
+ * the caller. For these triggers a record is written by the function
+ * dasd_eer_write_standard_trigger.
+ *
+ * The DASD_EER_STATECHANGE trigger is special since a sense subsystem
+ * status ccw need to be executed to gather the necessary sense data first.
+ * The dasd_eer_snss function will queue the SNSS request and the request
+ * callback will then call dasd_eer_write with the DASD_EER_STATCHANGE
+ * trigger.
+ *
+ * To avoid memory allocations at runtime, the necessary memory is allocated
+ * when the extended error reporting is enabled for a device (by
+ * dasd_eer_probe). There is one sense subsystem status request for each

-   Please send bug reports and support requests to <luc@saillard.org>.
-   The decompression routines have been implemented by reverse-engineering the

-/* This tables contains entries for the 730/740/750 (Kiara) camera, with
-   4 different qualities (no compression, low, medium, high).
-   It lists the bandwidth requirements for said mode by its alternate interface
-   number. An alternate of 0 means that the mode is unavailable.
-
-   There are 6 * 4 * 4 entries:
-     6 different resolutions subqcif, qsif, qcif, sif, cif, vga
-     6 framerates: 5, 10, 15, 20, 25, 30
-     4 compression modi: none, low, medium, high
-
-   When an uncompressed mode is not available, the next available compressed mode
-   will be chosen (unless the decompressor is absent). Sometimes there are only
-   1 or 2 compressed modes available; in that case entries are duplicated.

-/* This tables contains entries for the 675/680/690 (Timon) camera, with
-   4 different qualities (no compression, low, medium, high).
-   It lists the bandwidth requirements for said mode by its alternate interface
-   number. An alternate of 0 means that the mode is unavailable.
-
-   There are 6 * 4 * 4 entries:
-     6 different resolutions subqcif, qsif, qcif, sif, cif, vga
-     6 framerates: 5, 10, 15, 20, 25, 30
-     4 compression modi: none, low, medium, high
-
-   When an uncompressed mode is not available, the next available compressed mode
-   will be chosen (unless the decompressor is absent). Sometimes there are only
-   1 or 2 compressed modes available; in that case entries are duplicated.

 	  the problem.
-	- Enable the code for setting the NT4 compatibility flag when we start
-	  making NTFS 1.2 specific modifications.
+
+2.1.27 - Various bug fixes and cleanups.
+
+	- Fix two compiler warnings on Alpha.  Thanks to Andrew Morton for
+	  reporting them.
+	- Fix an (innocent) off-by-one error in the runlist code.
+	- Fix a buggette in an "should be impossible" case handling where we
+	  continued the attribute lookup loop instead of aborting it.
+	- Use buffer_migrate_page() for the ->migratepage function of all ntfs
+	  address space operations.
+	- Fix comparison of $MFT and $MFTMirr to not bail out when there are
+	  unused, invalid mft records which are the same in both $MFT and
+	  $MFTMirr.
+	- Add support for sparse files which have a compression unit of 0.
+	- Remove all the make_bad_inode() calls.  This should only be called
+	  from read inode and new inode code paths.
+	- Limit name length in fs/ntfs/unistr.c::ntfs_nlstoucs() to maximum
+	  allowed by NTFS, i.e. 255 Unicode characters, not including the
+	  terminating NULL (which is not stored on disk).
+	- Improve comments on file attribute flags in fs/ntfs/layout.h.
+	- Fix a bug in fs/ntfs/inode.c::ntfs_read_locked_index_inode() where we
+	  forgot to update a temporary variable so loading index inodes which
+	  have an index allocation attribute failed.
+	- Add a missing call to flush_dcache_mft_record_page() in
+	  fs/ntfs/inode.c::ntfs_write_inode().
+	- Handle the recently introduced -ENAMETOOLONG return value from
+	  fs/ntfs/unistr.c::ntfs_nlstoucs() in fs/ntfs/namei.c::ntfs_lookup().
+	- Semaphore to mutex conversion.  (Ingo Molnar)
 
 2.1.26 - Minor bug fixes and updates.

+ * Per-cpu incore superblock counters
+ *
+ * Simple concept, difficult implementation
+ *
+ * Basically, replace the incore superblock counters with a distributed per cpu
+ * counter for contended fields (e.g.  free block count).
+ *
+ * Difficulties arise in that the incore sb is used for ENOSPC checking, and
+ * hence needs to be accurately read when we are running low on space. Hence
+ * there is a method to enable and disable the per-cpu counters based on how
+ * much "stuff" is available in them.
+ *
+ * Basically, a counter is enabled if there is enough free resource to justify
+ * running a per-cpu fast-path. If the per-cpu counter runs out (i.e. a local
+ * ENOSPC), then we disable the counters to synchronise all callers and
+ * re-distribute the available resources.
+ *
+ * If, once we redistributed the available resources, we still get a failure,
+ * we disable the per-cpu counter and go through the slow path.
+ *
+ * The slow path is the current xfs_mod_incore_sb() function.  This means that
+ * when we disable a per-cpu counter, we need to drain it's resources back to
+ * the global superblock. We do this after disabling the counter to prevent
+ * more threads from queueing up on the counter.
+ *
+ * Essentially, this means that we still need a lock in the fast path to enable
+ * synchronisation between the global counters and the per-cpu counters. This
+ * is not a problem because the lock will be local to a CPU almost all the time
+ * and have little contention except when we get to ENOSPC conditions.
+ *
+ * Basically, this lock becomes a barrier that enables us to lock out the fast
+ * path while we do things like enabling and disabling counters and
+ * synchronising the counters.
+ *
+ * Locking rules:
+ *
+ * 	1. XFS_SB_LOCK() before picking up per-cpu locks
+ * 	2. per-cpu locks always picked up via for_each_online_cpu() order
+ * 	3. accurate counter sync requires XFS_SB_LOCK + per cpu locks
+ * 	4. modifying per-cpu counters requires holding per-cpu lock
+ * 	5. modifying global counters requires holding XFS_SB_LOCK
+ *	6. enabling or disabling a counter requires holding the XFS_SB_LOCK
+ *	   and _none_ of the per-cpu locks.
+ *
+ * Disabled counters are only ever re-enabled by a balance operation
+ * that results in more free resources per CPU than a given threshold.
+ * To ensure counters don't remain disabled, they are rebalanced when
+ * the global resource goes above a higher threshold (i.e. some hysteresis
+ * is present to prevent thrashing).
+ */
+
+/*
+ * hot-plug CPU notifier support.
+ *
+ * We cannot use the hotcpu_register() function because it does
+ * not allow notifier instances. We need a notifier per filesystem
+ * as we need to be able to identify the filesystem to balance
+ * the counters out. This is acheived by having a notifier block
+ * embedded in the xfs_mount_t and doing pointer magic to get the

+ * The SMP alternative tables can be kept after boot and contain both
+ * UP and SMP versions of the instructions to allow switching back to
+ * SMP at runtime, when hotplugging in a new CPU, which is especially
+ * useful in virtualized environments.
+ *
+ * The very common lock prefix is handled as special case in a

+/* msp3400 routing
+   ===============
+
+   The msp3400 has a complicated routing scheme with many possible
+   combinations. The details are all in the datasheets but I will try
+   to give a short description here.
+
+   Inputs
+   ======
+
+   There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+   to select which tuner input to use and which SCART input to use. The
+   selected tuner input, the selected SCART input and all I2S inputs go to
+   the DSP (the tuner input first goes through the demodulator).
+
+   The DSP handles things like volume, bass/treble, balance, and some chips
+   have support for surround sound. It has several outputs: MAIN, AUX, I2S
+   and SCART1/2. Each output can select which DSP input to use. So the MAIN
+   output can select the tuner input while at the same time the SCART1 output
+   uses the I2S input.
+
+   Outputs
+   =======
+
+   Most DSP outputs are also the outputs of the msp3400. However, the SCART
+   outputs of the msp3400 can select which input to use: either the SCART1 or
+   SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+   bypassing the DSP.
+
+   Summary
+   =======
+
+   So to specify a complete routing scheme for the msp3400 you will have to
+   specify in the 'input' field of the v4l2_routing struct:
+
+   1) which tuner input to use
+   2) which SCART input to use
+   3) which DSP input to use for each DSP output
+
+   And in the 'output' field of the v4l2_routing struct you specify:
+
+   1) which SCART input to use for each SCART output
+
+   Depending on how the msp is wired to the other components you can
+   ignore or mute certain inputs or outputs.
+
+   Also, depending on the msp version only a subset of the inputs or
+   outputs may be present. At the end of this header some tables are
+   added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+   1) the tuner (SIF) input
+   2) the SCART input
+   Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+   input, bits 4-7 are reserved.

 /**
- *	Swap map-handling functions
- *
- *	The swap map is a data structure used for keeping track of each page
- *	written to the swap.  It consists of many swap_map_page structures
- *	that contain each an array of MAP_PAGE_SIZE swap entries.
- *	These structures are linked together with the help of either the
- *	.next (in memory) or the .next_swap (in swap) member.
+ *	The following functions are used for tracing the allocated
+ *	swap pages, so that they can be freed in case of an error.
  *
- *	The swap map is created during suspend.  At that time we need to keep
- *	it in memory, because we have to free all of the allocated swap
- *	entries if an error occurs.  The memory needed is preallocated
- *	so that we know in advance if there's enough of it.
- *
- *	The first swap_map_page structure is filled with the swap entries that
- *	correspond to the first MAP_PAGE_SIZE data pages written to swap and
- *	so on.  After the all of the data pages have been written, the order
- *	of the swap_map_page structures in the map is reversed so that they
- *	can be read from swap in the original order.  This causes the data
- *	pages to be loaded in exactly the same order in which they have been
- *	saved.
- *
- *	During resume we only need to use one swap_map_page structure
- *	at a time, which means that we only need to use two memory pages for
- *	reading the image - one for reading the swap_map_page structures
- *	and the second for reading the data pages from swap.
+ *	The functions operate on a linked bitmap structure defined
