err.h: add helper function to simplify pointer error checking

2009-12-15T16:53:27Z

There are quite a few instances in the kernel of checks of pointers both against NULL and against the errno range, handling both cases identically. This additional helper function would simplify such code. [akpm@linux-foundation.org: build fix] Signed-off-by: Phil Carmody Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Add an ERR_CAST() function to complement ERR_PTR and co.

2008-02-07T16:42:25Z

Add an ERR_CAST() function to complement ERR_PTR and co. for the purposes of casting an error entyped as one pointer type to an error of another pointer type whilst making it explicit as to what is going on. This provides a replacement for the ERR_PTR(PTR_ERR(p)) construct. Signed-off-by: David Howells Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] consistently use MAX_ERRNO in __syscall_return

[PATCH] Fix IS_ERR Threshold Value

2006-07-01T16:56:03Z

o Raise the maximum error number in IS_ERR_VALUE to 4095. o Make that number available as a new constant MAX_ERRNO. Signed-off-by: Ralf Baechle Cc: "H. Peter Anvin" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Fix get_unmapped_area sanity tests

2005-05-20T05:43:37Z

As noted by Chris Wright, we need to do the full range of tests regardless of whether MAP_FIXED is set or not, so re-organize get_unmapped_area() slightly to do the sanity checks unconditionally.

[PATCH] mark IS_ERR as unlikely()

2004-08-23T06:04:49Z

It seems fair to assume that it is always unlikely that IS_ERR will return true. This patch changes the gcc-3.4-generated kernel text by ~500 bytes (less) so it's fair to assume that the compiler is indeed propagating unlikeliness out of inline functions.

[PATCH] includes cleanup, 2nd try.

Big bits first, I'll redo the smaller bits tomorrow after some sleep. Same as last time, rediffed against pre5
