saner FASYNC handling on file close

2008-11-01T16:49:46Z

As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore. Signed-off-by: Al Viro Signed-off-by: Linus Torvalds

tracehook: wait_task_inactive

2008-07-26T19:00:09Z

This extends wait_task_inactive() with a new argument so it can be used in a "soft" mode where it will check for the task changing state unexpectedly and back off. There is no change to existing callers. This lays the groundwork to allow robust, noninvasive tracing that can try to sample a blocked thread but back off safely if it wakes up.

on_each_cpu(): kill unused 'retry' parameter

2008-06-26T09:24:38Z

It's not even passed on to smp_call_function() anymore, since that was removed. So kill it. Acked-by: Jeremy Fitzhardinge Reviewed-by: Paul E. McKenney Signed-off-by: Jens Axboe

smp_call_function: get rid of the unused nonatomic/retry argument

2008-06-26T09:24:35Z

It's never used and the comments refer to nonatomic and retry interchangably. So get rid of it. Acked-by: Jeremy Fitzhardinge Signed-off-by: Jens Axboe

[IA64] perfmon: fix async exit bug

2008-06-11T22:24:13Z

Move the cleanup of the async queue to the close callback from the flush callback. This avoids losing asynchronous overflow notifications when the file descriptor is shared by multiple processes and one terminates. Signed-off-by: Stephane Eranian Signed-off-by: Tony Luck

[IA64] fix file and descriptor handling in perfmon

2008-05-01T21:36:36Z

Races galore... General rule: as soon as it's in descriptor table, it's over; another thread might have started IO on it/dup2() it elsewhere/dup2() something *over* it/etc. fd_install() is the very last step one should take - it's a point of no return. Besides, the damn thing leaked on failure exits... Signed-off-by: Al Viro Signed-off-by: Tony Luck

ia64: use non-racy method for proc entries creation

[IA64] minor irq handler cleanups

2008-04-22T15:56:58Z

- remove unused 'irq' argument from pfm_do_interrupt_handler() - remove pointless cast to void* - add KERN_xxx prefix to printk() - remove braces around singleton C statement - in tioce_provider.c, start tioce_dma_consistent() and tioce_error_intr_handler() function declarations in column 0 This change's main purpose is to prepare for the patchset in jgarzik/misc-2.6.git#irq-remove, that explores removal of the never-used 'irq' argument in each interrupt handler.
