Trond Myklebust 5cc6b7acf5 NFSv4: Fix a deadlock between nfs4_open_recover_helper() and delegreturn ... [ Upstream commit 51069e4aef ] If we're asked to recover open state while a delegation return is outstanding, then the state manager thread cannot use a cached open, so if the server returns a delegation, we can end up deadlocked behind the pending delegreturn. To avoid this problem, let's just ask the server not to give us a delegation unless we're explicitly reclaiming one.
