Subject: [PATCH v2 5/5] NFS: Don't try to reclaim delegation open state if recovery failed
Date: Wed, 12 Nov 2014 17:31:54 -0500	[thread overview]
Message-ID: <1415831514-47005-6-git-send-email-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <1415831514-47005-5-git-send-email-trond.myklebust@primarydata.com>

If state recovery failed, then we should not attempt to reclaim delegated
state.
