Only the first patch is really applicable for stable. It adds appropriate socket locks so lockdep doesn't complain if tuntap's ioctls modify the filters on the socket.
Rest of the patches tighten the rcu dereference socket lock checks. Last patch fixes missing rcu_read_locks which were discovered by this change. Certainly there are more to come.
