kref: Add a kref_sub function

2010-11-22T03:25:13Z

Makes it possible to optimize batched multiple unrefs. Initial user will be drivers/gpu/ttm which accumulates unrefs to be processed outside of atomic code. Signed-off-by: Thomas Hellstrom Signed-off-by: Dave Airlie

kref: remove kref_set

2010-05-21T16:37:29Z

Of the three uses of kref_set in the kernel: One really should be kref_put as the code is letting go of a reference, Two really should be kref_init because the kref is being initialised. This suggests that making kref_set available encourages bad code. So fix the three uses and remove kref_set completely.

headers: kref.h redux

2009-09-26T17:17:19Z

* remove asm/atomic.h inclusion from kref.h -- not needed, linux/types.h is enough for atomic_t * remove linux/kref.h inclusion from files which do not need it. Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds

Remove "#ifdef KERNEL" checks from unexported headers

2008-04-30T15:29:54Z

Remove the "#ifdef __KERNEL__" tests from unexported header files in linux/include whose entire contents are wrapped in that preprocessor test. Signed-off-by: Robert P. J. Day Cc: David Woodhouse Cc: Sam Ravnborg Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kref: add kref_set()

2008-01-25T04:40:05Z

This adds kref_set() to the kref api for future use by people who really know what they are doing with krefs... From: Evgeniy Polyakov Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

[PATCH] kref: make kref_put return if this was the last put call.

This is needed for the upcoming klist code from Pat. Signed-off-by: Greg Kroah-Hartman

Use "ifdef" rather than "if" to test for KERNEL

2004-09-01T09:24:37Z

Both work, but the latter can cause warnings in user space from compilers that don't like using undefined identifiers in preprocessor expressions (quite reasonable). Pointed out by Randy Dunlap.

Allow the compiler to notice "constant" header file.

2004-08-31T14:07:07Z

Both gcc and sparse will speed up tokenization by noticing when a header file is protected by the standard preprocessor #ifndef .. #endif exclusion. However, that requires that the headers actually _use_ that standard exclusion. Some did their own little broken dance.

KREF: make kref_get() return void as it makes sense to do so.

Thanks to Kiran for bugging me to do this. Signed-off-by: Greg Kroah-Hartman
