2006-03-23	[PATCH] sem2mutex: jbd, j_checkpoint_mutex	Arjan van de Ven	1	-2/+2
	Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.

2005-10-28	[PATCH] gfp_t: fs/*	Al Viro	1	-1/+1
	- ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

2005-09-07	[PATCH] Change ll_rw_block() calls in JBD	Jan Kara	1	-1/+1
	We must be sure that the current data in buffer are sent to disk. Hence we have to call ll_rw_block() with SWRITE. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-07	[PATCH] kjournald: missing JFS_UNMOUNT check	Mark Fasheh	1	-0/+2
	It seems that kjournald() may be missing a check of the JFS_UNMOUNT flag before calling schedule(). This showed up in testing of OCFS2 recovery where our recovery thread would hang in journal_kill_thread() called from journal_destroy() because kjournald never got a chance to read the flag to shut down before the schedule(). Zach pointed out the missing check which led me to hack up this trivial patch. It's been tested many times now and I have yet to reproduce the hang, which was happening very regularly before. <mild rant> I'm guessing that we could really use some wait_event() calls with helper functions in, well, most of jbd these days which would make a ton of the wait code there vastly cleaner. </mild rant> As for why this doesn't happen in ext3 (or OCFS2 during normal mount/unmount of the local nodes journal), I think it may that the specific timing of events in the ocfs2 recovery thread exposes a race there. Because ocfs2_replay_journal() is only interested in playing back the journal, initialization and shutdown happen very quicky with no other metadata put into that specific journal.

2005-09-07	[PATCH] fs/jbd/: cleanups	Adrian Bunk	1	-20/+14
	This patch contains the following cleanups: - make needlessly global functions static - journal.c: remove the unused global function __journal_internal_check and move the check to journal_init - remove the following write-only global variable: - journal.c: current_journal - remove the following unneeded EXPORT_SYMBOL: - journal.c: journal_recover Signed-off-by: Adrian Bunk <bunk@stusta.de> Acked-by: Andreas Dilger <adilger@clusterfs.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-06-25	[PATCH] Cleanup patch for process freezing	Christoph Lameter	1	-2/+2
	1. Establish a simple API for process freezing defined in linux/include/sched.h: frozen(process) Check for frozen process freezing(process) Check if a process is being frozen freeze(process) Tell a process to freeze (go to refrigerator) thaw_process(process) Restart process frozen_process(process) Process is frozen now 2. Remove all references to PF_FREEZE and PF_FROZEN from all kernel sources except sched.h 3. Fix numerous locations where try_to_freeze is manually done by a driver 4. Remove the argument that is no longer necessary from two function calls. 5. Some whitespace cleanup 6. Clear potential race in refrigerator (provides an open window of PF_FREEZE cleared before setting PF_FROZEN, recalc_sigpending does not check PF_FROZEN). This patch does not address the problem of freeze_processes() violating the rule that a task may only modify its own flags by setting PF_FREEZE. This is not clean in an SMP environment. freeze(process) is therefore not SMP safe! Signed-off-by: Christoph Lameter <christoph@lameter.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-0/+2003
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
