Subject: [PATCH v4 14/20] NFSv4: nfs4_do_handle_exception() handle revoke/expiry of a single stateid
Date: Thu, 15 Sep 2016 12:45:54 -0400	[thread overview]
Message-ID: <1473957960-10001-15-git-send-email-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <1473957960-10001-14-git-send-email-trond.myklebust@primarydata.com>

If we're not yet sure that all state has expired or been revoked, we
should try to do a minimal recovery on just the one stateid.
