From 07ab67c8d0d7c1021343b7d5c045033d6bf7be69 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 19 May 2005 22:43:37 -0700 Subject: Fix get_unmapped_area sanity tests 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. --- include/linux/err.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'include/linux/err.h') diff --git a/include/linux/err.h b/include/linux/err.h index 17c55df13615..ff71d2af5da3 100644 --- a/include/linux/err.h +++ b/include/linux/err.h @@ -13,6 +13,8 @@ * This should be a per-architecture thing, to allow different * error and pointer decisions. */ +#define IS_ERR_VALUE(x) unlikely((x) > (unsigned long)-1000L) + static inline void *ERR_PTR(long error) { return (void *) error; @@ -25,7 +27,7 @@ static inline long PTR_ERR(const void *ptr) static inline long IS_ERR(const void *ptr) { - return unlikely((unsigned long)ptr > (unsigned long)-1000L); + return IS_ERR_VALUE((unsigned long)ptr); } #endif /* _LINUX_ERR_H */ -- cgit v1.2.3
