3.5.7.10 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Jan Kara <j...@suse.cz>
commit 35e5cbc0af240778e61113286c019837e06aeec6 upstream.
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().
