Subject: [PATCH]: (off 2.5.22) replacing __builtin_expect with unlikely in Alpha headers
Date: Wed, 19 Jun 2002 14:39:36 +0530 [thread overview]
Message-ID: <3D104A50.24C00206@cisco.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 244 bytes --]
This fix should remove __builtin_expect () and replace it with
unlikely () in include/asm-alpha/rwsem.h
This should be cool since rwsem.h already includes
include/linux/compiler.h
Files changed :
include/asm-alpha/rwsem.h
