I have made more testing and it was actually my code which cause 013 not
fail. It is still pretty strange. I have made code for new mount api (fs
context) and 013 still get deadlock but still test will pass. This only
happends if acl is on. Though this is intresting why this happends. I
will not use more time for this now. I will try to focus fs context
mount api for now.
