From 35e5cbc0af240778e61113286c019837e06aeec6 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Fri, 29 Mar 2013 15:39:16 +0100 Subject: reiserfs: Fix warning and inode leak when deleting inode with xattrs After commit 21d8a15a (lookup_one_len: don't accept . and ..) reiserfs started failing to delete xattrs from inode. This was due to a buggy test for '.' and '..' in fill_with_dentries() which resulted in passing '.' and '..' entries to lookup_one_len() in some cases. That returned error and so we failed to iterate over all xattrs of and inode. Fix the test in fill_with_dentries() along the lines of the one in lookup_one_len().
