It should go into -stable if it's not already there. From: Alexander Nyberg I looked at some of the oops reports against keyrings, I think the problem is that the search isn't restarted after dropping the key_user_lock, *p will still be NULL when we get back to try_again and look through the tree. It looks like the intention was that the search start over from scratch.
