From: Julia Lawall <[EMAIL PROTECTED]> In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, 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/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Julia Lawall <[EMAIL PROTECTED]> --- diff -u -p a/fs/ocfs2/aops.c b/fs/ocfs2/aops.c --- a/fs/ocfs2/aops.c 2008-02-05 20:56:02.000000000 +0100 +++ b/fs/ocfs2/aops.c 2008-02-26 08:16:47.000000000 +0100 @@ -257,7 +257,7 @@ static int ocfs2_readpage_inline(struct struct ocfs2_super *osb = OCFS2_SB(inode->i_sb); BUG_ON(!PageLocked(page)); - BUG_ON(!OCFS2_I(inode)->ip_dyn_features & OCFS2_INLINE_DATA_FL); + BUG_ON(!(OCFS2_I(inode)->ip_dyn_features & OCFS2_INLINE_DATA_FL)); ret = ocfs2_read_block(osb, OCFS2_I(inode)->ip_blkno, &di_bh, OCFS2_BH_CACHED, inode); _______________________________________________ Ocfs2-devel mailing list [email protected] http://oss.oracle.com/mailman/listinfo/ocfs2-devel
