[PATCH] avoid one conditional branch in touch_atime()
I added IS_NOATIME(inode) macro definition in include/linux/fs.h, true if the inode superblock is marked readonly or noatime. This new macro is then used in touch_atime() instead of separatly testing MS_RDONLY and MS_NOATIME Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
