The patch titled vfs: O_* bit numbers uniqueness check fix has been removed from the -mm tree. Its filename was vfs-o_-bit-numbers-uniqueness-check-fix.patch This patch was dropped because it was folded into vfs-o_-bit-numbers-uniqueness-check.patch The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: vfs: O_* bit numbers uniqueness check fix From: Wu Fengguang <fengguang.wu@xxxxxxxxx> Follow the comment by Andreas: It's non-obvious why there are 18 flags listed here, but the hweight is only 17? Presumably this is because O_RDONLY has value 0, but that should at least be listed in a comment, or the test could be written more explicitly, like: BUILD_BUG_ON(18 - 1 /* for O_RDONLY being 0 */ != HWEIGHT32( Signed-off-by: Wu Fengguang <fengguang.wu@xxxxxxxxx> Cc: Andreas Dilger <adilger@xxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- fs/fcntl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN fs/fcntl.c~vfs-o_-bit-numbers-uniqueness-check-fix fs/fcntl.c --- a/fs/fcntl.c~vfs-o_-bit-numbers-uniqueness-check-fix +++ a/fs/fcntl.c @@ -742,7 +742,7 @@ EXPORT_SYMBOL(kill_fasync); static int __init fcntl_init(void) { /* please add new bits here to ensure allocation uniqueness */ - BUILD_BUG_ON(17 != HWEIGHT32( + BUILD_BUG_ON(18 - 1 /* for O_RDONLY being 0 */ != HWEIGHT32( O_RDONLY | O_WRONLY | O_RDWR | O_CREAT | O_EXCL | O_NOCTTY | O_TRUNC | O_APPEND | O_NONBLOCK | _ Patches currently in -mm which might be from fengguang.wu@xxxxxxxxx are linux-next.patch include-linux-fsh-complete-hexification-of-fmode_-constants.patch vfs-o_-bit-numbers-uniqueness-check.patch vfs-o_-bit-numbers-uniqueness-check-fix.patch vfs-o_-bit-numbers-uniqueness-check-fix-2.patch vfs-introduce-fmode_neg_offset-for-allowing-negative-f_pos.patch vmscan-prevent-get_scan_ratio-rounding-errors.patch readaheadc-fix-comment.patch fs-writeback-check-sync-bit-earlier-in-inode_wait_for_writeback.patch vfs-add-super-operation-writeback_inodes.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
