2007-10-19Task Control Groups: add tasks file interfacePaul Menage
Add the per-directory "tasks" file for cgroupfs mounts; this allows the user to determine which tasks are members of a cgroup by reading a cgroup's "tasks", and to move a task into a cgroup by writing its pid to its "tasks".

2007-10-19Task Control Groups: basic task cgroup frameworkPaul Menage
Generic Process Control Groups -------------------------- There have recently been various proposals floating around for resource management/accounting and other task grouping subsystems in the kernel, including ResGroups, User BeanCounters, NSProxy cgroups, and others. These all need the basic abstraction of being able to group together multiple processes in an aggregate, in order to track/limit the resources permitted to those processes, or control other behaviour of the processes, and all implement this grouping in different ways. This patchset provides a framework for tracking and grouping processes into arbitrary "cgroups" and assigning arbitrary state to those groupings, in order to control the behaviour of the cgroup as an aggregate. The intention is that the various resource management and virtualization/cgroup efforts can also become task cgroup clients, with the result that: - the userspace APIs are (somewhat) normalised - it's easier to test e.g. the ResGroups CPU controller in conjunction with the BeanCounters memory controller, or use either of them as the resource-control portion of a virtual server system. - the additional kernel footprint of any of the competing resource management systems is substantially reduced, since it doesn't need to provide process grouping/containment, hence improving their chances of getting into the kernel This patch: Add the main task cgroups framework - the cgroup filesystem, and the basic structures for tracking membership and associating subsystem state objects to tasks.

2007-10-19cpuset: zero malloc - revert the old cpuset fixPaul Jackson
The cpuset code to present a list of tasks using a cpuset to user space could write to an array that it had kmalloc'd, after a kmalloc request of zero size. The problem was that the code didn't check for writes past the allocated end of the array until -after- the first write. This is a race condition that is likely rare -- it would only show up if a cpuset went from being empty to having a task in it, during the brief time between the allocation and the first write. Prior to roughly 2.6.22 kernels, this was also a benign problem, because a zero kmalloc returned a few usable bytes anyway, and no harm was done with the bogus write. With the 2.6.22 kernel changes to make issue a warning if code tries to write to the location returned from a zero size allocation, this problem is no longer benign. This cpuset code would occassionally trigger that warning. The fix is trivial -- check before storing into the array, not after, whether the array is big enough to hold the store. Cc: "Eric W.

2007-10-19reiserfs: ignore on disk s_bmap_nr valueJeff Mahoney
Implement support for file systems larger than 8 TiB. The reiserfs superblock contains a 16 bit value for counting the number of bitmap blocks. The rest of the disk format supports file systems up to 2^32 blocks, but the bitmap block limitation artificially limits this to 8 TiB with a 4KiB block size. Rather than trust the superblock's 16-bit bitmap block count, we calculate it dynamically based on the number of blocks in the file system. When an incorrect value is observed in the superblock, it is zeroed out, ensuring that older kernels will not be able to mount the file system. Userspace support has already been implemented and shipped in reiserfsprogs 3.6.20.

2007-10-19reiserfs: remove first_zero_hintJeff Mahoney
The first_zero_hint metadata caching was never actually used, and it's of dubious optimization quality. This patch removes it. It doesn't actually shrink the size of the reiserfs_bitmap_info struct, since that doesn't work with block sizes larger than 8K. There was a big fixme in there, and with all the work lately in allowing block size > page size, I might as well kill the fixme as well.

2007-10-19reiserfs: fix usage of signed ints for block numbersJeff Mahoney
Do a quick signedness check for block numbers. There are a number of places where signed integers are used for block numbers, which limits the usable file system size to 8 TiB. The disk format, excepting a problem which will be fixed in the following patch, supports file systems up to 16 TiB in size. This patch cleans up those sites so that we can enable the full usable size.

2007-10-19JBD: Fix JBD warnings when compiling with CONFIG_JBD_DEBUGJose R. Santos
Note from Mingming's JBD2 fix: Noticed all warnings are occurs when the debug level is 0. Then found the "jbd2: Move jbd2-debug file to debugfs" patch http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0f49d5d019afa4e94253bfc92f0daca3badb990b changed the jbd2_journal_enable_debug from int type to u8, makes the jbd_debug comparision is always true when the debugging level is 0. Thus the compile warning occurs. Thought about changing the jbd2_journal_enable_debug data type back to int, but can't, because the jbd2-debug is moved to debug fs, where calling debugfs_create_u8() to create the debugfs entry needs the value to be u8 type. Even if we changed the data type back to int, the code is still buggy, kernel should not print jbd2 debug message if the jbd2_journal_enable_debug is set to 0. But this is not the case. The fix is change the level of debugging to 1. The same should fixed in ext3/JBD, but currently ext3 jbd-debug via /proc fs is broken, so we probably should fix it all together.

2007-10-19jbd: config_jbd_debug cannot create /proc entryJose R. Santos
The jbd-debug file used to be located in /proc/sys/fs/jbd-debug, but create_proc_entry() does not do lookups on file names that are more that one directory deep. This causes the entry creation to fail and hence, no proc file is created. Instead of fixing this on procfs might as well move the jbd2-debug file to debugfs which would be the preferred location for this kind of tunable. The new location is now /sys/kernel/debug/jbd/jbd-debug. [akpm@linux-foundation.org: zillions of cleanups] Signed-off-by: Jose R.

2007-10-19Console keyboard events and accessibilitySamuel Thibault
Some blind people use a kernel engine called Speakup which uses hardware synthesis to speak what gets displayed on the screen. They use the PC keyboard to control this engine (start/stop, accelerate, ...) and also need to get keyboard feedback (to make sure to know what they are typing, the caps lock status, etc.) Up to now, the way it was done was very ugly. Below is a patch to add a notifier list for permitting a far better implementation, see ChangeLog above for details. You may wonder why this can't be done at the input layer. The problem is that what people want to monitor is the console keyboard, i.e. all input keyboards that got attached to the console, and with the currently active keymap (i.e. keysyms, not only keycodes). This adds a keyboard notifier that such modules can use to get the keyboard events and possibly eat them, at several stages: - keycodes: even before translation into keysym. - unbound keycodes: when no keysym is bound. - unicode: when the keycode would get translated into a unicode character. - keysym: when the keycode would get translated into a keysym. - post_keysym: after the keysym got interpreted, so as to see the result (caps lock, etc.) This also provides access to k_handler so as to permit simulation of keypresses.
