This patch adds a new (Kbuild) Makefile variable KBUILD_EXTRA_SYMBOLS.

2008-04-25kbuild: support loading extra symbols in modpostRichard Hacker
This patch adds a new command line option -E to modpost, expecting a symbol file as an argument which is read prior to symbol processing. -E can be supplied multiple times for as many files as is needed. When building kernel modules that depend on other modules not in the main kernel tree, modpost complains about undefined symbols: # make -C /path/to/linux/kernel M=/path/to/my/module ... Building modules, stage 2. .... WARNING: "rt_copy_buf" [/home/rich/osc_etl_rtw/osc_kmod.ko] undefined! ...etc This situation occurs when modpost processes the new module's symbols. When it finds symbols not exported by the mainline kernel, it issues this warning. The patch adds a new command line option -e to modpost which expects a symbol file as an argument. The symbols listed in this file are added to modpost's symbol tables during startup. -e can be supplied as often as required. This patch works together with the second patch. It introduces a new make variable, KBUILD_EXTRA_SYMBOLS, which is used when calling modpost. Signed-off-by: Richard Hacker <lerichi@gmx.net> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2008-04-25Add option to enable -Wframe-larger-than= on gcc 4.4Andi Kleen
Add option to enable -Wframe-larger-than= on gcc 4.4 gcc mainline (upcoming 4.4) added a new -Wframe-larger-than=... option to warn at build time about too large stack frames. Add a config option to enable this warning, since this very useful for the kernel. I choose (somewhat arbitarily) 2048 as default warning threshold for 64bit and 1024 as default for 32bit architectures. With some research and fixing all the code for smaller values these defaults should be probably lowered. With the default allyesconfigs have some new warnings, but I think that is all code that should be just fixed. At some point (when gcc 4.4 is released and widely used) this should obsolete make checkstack Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2008-04-25locks: don't call ->copy_lock methods on return of conflicting locksJ. Bruce Fields
The file_lock structure is used both as a heavy-weight representation of an active lock, with pointers to reference-counted structures, etc., and as a simple container for parameters that describe a file lock. The conflicting lock returned from __posix_lock_file is an example of the latter; so don't call the filesystem or lock manager callbacks when copying to it. This also saves the need for an unnecessary locks_init_lock in the nfsv4 server. Thanks to Trond for pointing out the error. Signed-off-by: J.

2008-04-25lockd: unlock lockd locks associated with a given server ipWendy Cheng
For high-availability NFS service, we generally need to be able to drop file locks held on the exported filesystem before moving clients to a new server. Currently the only way to do that is by shutting down lockd entirely, which is often undesireable (for example, if you want to continue exporting other filesystems). This patch allows the administrator to release all locks held by clients accessing the client through a given server ip address, by echoing that address to a new file, /proc/fs/nfsd/unlock_ip, as in: shell> echo 10.1.1.2 > /proc/fs/nfsd/unlock_ip The expected sequence of events can be: 1. Tear down the IP address 2. Unexport the path 3. Write IP to /proc/fs/nfsd/unlock_ip to unlock files 4. Signal peer to begin take-over. For now we only support IPv4 addresses and NFSv2/v3 (NFSv4 locks are not affected). Also, if unmounting the filesystem is required, we assume at step 3 that clients using the given server ip are the only clients holding locks on the given filesystem; otherwise, an additional patch is required to allow revoking all locks held by lockd on a given filesystem.

2008-04-25ieee1394: rawiso: requeue packet for transmission after skipped cyclePieter Palmers
As it seems, some host controllers have issues that can cause them to skip cycles now and then when using large packets. I suspect that this is due to DMA not succeeding in time. If the transmit fifo can't contain more than one packet (big packets), the DMA should provide a new packet each cycle (125us). I am under the impression that my current PCI express test system can't guarantee this. In any case, the patch tries to provide a workaround as follows: The DMA program descriptors are modified such that when an error occurs, the DMA engine retries the descriptor the next cycle instead of stalling. This way no data is lost. The side effect of this is that packets are sent with one cycle delay. This however might not be that much of a problem for certain protocols (e.g. AM824). If they use padding packets for e.g. rate matching they can drop one of those to resync the streams. The amount of skips between two userspace wakeups is counted. This number is then propagated to userspace through the upper 16 bits of the 'dropped' parameter. This allows unmodified userspace applications due to the following: 1) libraw simply passes this dropped parameter to the user application 2) the meaning of the dropped parameter is: if it's nonzero, something bad has happened. The actual value of the parameter at this moment does not have a specific meaning. A libraw client can then retrieve the number of skipped cycles and account for them if needed.
