[PATCH] Numerous fixes to kernel-doc info in source files.

2007-02-11T18:51:32Z

A variety of (mostly) innocuous fixes to the embedded kernel-doc content in source files, including: * make multi-line initial descriptions single line * denote some function names, constants and structs as such * change erroneous opening '/*' to '/**' in a few places * reword some text for clarity Signed-off-by: Robert P.

[PATCH] memory ordering in __kfifo primitives

2006-09-29T16:18:13Z

Both __kfifo_put() and __kfifo_get() have header comments stating that if there is but one concurrent reader and one concurrent writer, locking is not necessary. This is almost the case, but a couple of memory barriers are needed. Another option would be to change the header comments to remove the bit about locking not being needed, and to change the those callers who currently don't use locking to add the required locking. The attachment analyzes this approach, but the patch below seems simpler. Signed-off-by: Paul E. McKenney Cc: Stelian Pop Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] gfp flags annotations - part 1

2005-10-08T22:00:57Z

- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better. Signed-off-by: Al Viro Signed-off-by: Linus Torvalds

Mark "gfp" masks as "unsigned int" and use __nocast to find violations.

This makes it hard(er) to mix argument orders by mistake for things like kmalloc() and friends, since silent integer promotion is now caught by sparse.

[PATCH] fix wrong kfifo_init buffer size argument

2004-11-04T04:08:40Z

kfifo_alloc tries to round up the buffer size to the next power of two. But it accidently uses the original size when calling kfifo_init, which will BUG. Acked-by: Stelian Pop Signed-off-by: Martin Waitz Signed-off-by: Linus Torvalds
