2008-08-26	sched: add kernel doc for the completion, fix kernel-doc-nano-HOWTO.txt	Kevin Diggs	1	-0/+41
	This patch adds kernel doc for the completion feature. An error in the split-man.pl PERL snippet in kernel-doc-nano-HOWTO.txt is also fixed. Signed-off-by: Kevin Diggs <kevdig@hypersurf.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-08-15	completions: uninline try_wait_for_completion and completion_done	Dave Chinner	1	-44/+2
	m68k fails to build with these functions inlined in completion.h. Move them out of line into sched.c and export them to avoid this problem.

2008-08-13	[XFS] extend completions to provide XFS object flush requirements	David Chinner	1	-0/+45
	XFS object flushing doesn't quite match existing completion semantics. It mixed exclusive access with completion. That is, we need to mark an object as being flushed before flushing it to disk, and then block any other attempt to flush it until the completion occurs. We do this but adding an extra count to the completion before we start using them. However, we still need to determine if there is a completion in progress, and allow no-blocking attempts fo completions to decrement the count. To do this we introduce: int try_wait_for_completion(struct completion x) returns a failure status if done == 0, otherwise decrements done to zero and returns a "started" status. This is provided to allow counted completions to begin safely while holding object locks in inverted order. int completion_done(struct completion x) returns 1 if there is no waiter, 0 if there is a waiter (i.e. a completion in progress). This replaces the use of semaphores for providing this exclusion and completion mechanism.

2007-10-24	sched: fix fastcall mismatch in completion APIs	Ingo Molnar	1	-9/+9
	Jeff Dike noticed that wait_for_completion_interruptible()'s prototype had a mismatched fastcall. Fix this by removing the fastcall attributes from all the completion APIs. Found-by: Jeff Dike <jdike@linux.intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2006-07-10	[PATCH] lockdep: clean up completion initializer in smpboot.c	Ingo Molnar	1	-1/+4
	Clean up lockdep on-stack-completion initializer. (This also removes the dependency on waitqueue_lock_key.) Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-07-03	[PATCH] lockdep: add DECLARE_COMPLETION_ONSTACK() API	Ingo Molnar	1	-0/+12
	lockdep needs to have the waitqueue lock initialized for on-stack waitqueues implicitly initialized by DECLARE_COMPLETION(). Introduce the API. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-0/+42
	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!
