sched: add kernel doc for the completion, fix kernel-doc-nano-HOWTO.txt

2008-08-26T08:26:54Z

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 Signed-off-by: Ingo Molnar

completions: uninline try_wait_for_completion and completion_done

2008-08-15T15:35:44Z

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. Signed-off-by: Dave Chinner Cc: Geert Uytterhoeven Cc: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[XFS] extend completions to provide XFS object flush requirements

2008-08-13T06:40:43Z

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.

sched: fix fastcall mismatch in completion APIs

2007-10-24T16:23:48Z

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 Signed-off-by: Ingo Molnar

[PATCH] lockdep: clean up completion initializer in smpboot.c

2006-07-10T20:24:14Z

Clean up lockdep on-stack-completion initializer. (This also removes the dependency on waitqueue_lock_key.) Signed-off-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] lockdep: add DECLARE_COMPLETION_ONSTACK() API

2006-07-03T22:27:00Z

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 Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] completion API additions

2005-01-21T00:08:46Z

Adds 3 new completion API calls, which are a straightforward extension of the current APIs: int wait_for_completion_interruptible(struct completion *x); unsigned long wait_for_completion_timeout(struct completion *x, unsigned long timeout); unsigned long wait_for_completion_interruptible_timeout( struct completion *x, unsigned long timeout); This enables the conversion of more semaphore-using code to completions. There is code that cannot be converted right now (and is forced to use semaphores) because these primitives are missing. Thomas Gleixner has a bunch of patches to make use of them.

[PATCH] tcore-fixes-2.5.50-E6

2002-12-02T00:29:39Z

This fixes threaded coredumps and streamlines the code. The old code caused crashes and hung coredumps. The new code has been tested for some time already and appears to be robust. Changes: - the code now uses completions instead of a semaphore and a waitqueue, attached to mm_struct: /* coredumping support */ int core_waiters; struct completion *core_startup_done, core_done; - extended the completion concept with a 'complete all' call - all pending threads are woken up in that case. - core_waiters is a plain integer now - it's always accessed from under the mmap_sem. It's also used as the fastpath-check in the sys_exit() path, instead of ->dumpable (which was incorrect). - got rid of the ->core_waiter task flag - it's not needed anymore.
