From acc1f3ede977bf189b332874beeadf48c01544c5 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 4 Mar 2008 14:29:20 -0800 Subject: fs/reiserfs/super.c: correct use of ! and & In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337 ("wmi: (!x & y) strikes again"), a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // Signed-off-by: Julia Lawall Cc: Chris Mason Cc: Jeff Mahoney Cc: Jan Kara Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/reiserfs/super.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/reiserfs/super.c') diff --git a/fs/reiserfs/super.c b/fs/reiserfs/super.c index 6841452e0de..393cc22c171 100644 --- a/fs/reiserfs/super.c +++ b/fs/reiserfs/super.c @@ -2031,7 +2031,7 @@ static int reiserfs_quota_on(struct super_block *sb, int type, int format_id, return -EXDEV; } /* We must not pack tails for quota files on reiserfs for quota IO to work */ - if (!REISERFS_I(nd.path.dentry->d_inode)->i_flags & i_nopack_mask) { + if (!(REISERFS_I(nd.path.dentry->d_inode)->i_flags & i_nopack_mask)) { reiserfs_warning(sb, "reiserfs: Quota file must have tail packing disabled."); path_put(&nd.path); -- cgit
