[PATCH] reiserfs: Fix warning and inode leak when deleting inode with xattrs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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().
