3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Trond Myklebust <trond.mykleb...@netapp.com>
commit 2b1bc308f492589f7d49012ed24561534ea2be8c upstream.
If the state recovery machinery is triggered by the call to
nfs4_async_handle_error() then we can deadlock.
