The first is a fix for a race that can causes oopses under the right circumstances, and that someone just recently encountered. The second is a fix that removes the possibility of creating unbounded chains in the mount hash table. After a lot of back and forth this fix has finally matured into something mergeable. Past that are several small trivial correct fixes. A real issue that was blocking development of an out of tree driver, but does not appear to have caused any actual problems for in-tree code. A potential deadlock that was reported by lockdep. And a deadlock people have experienced and took the time to track down caused by a cleanup that removed the code to drop a reference count. Andrei Vagin (1): pid: fix lockdep deadlock warning due to ucount_lock Eric W.
