Subject: [PATCH] NFSv4: don't mark all open state for recovery when handling recallable state revoked flag
Date: Thu,  2 May 2019 13:31:08 -0400	[thread overview]
Message-ID: <20190502173108.8796-1-smayhew@redhat.com> (raw)

Only delegations and layouts can be recalled, so it shouldn't be
necessary to recover all opens when handling the status bit
SEQ4_STATUS_RECALLABLE_STATE_REVOKED.  We'll still wind up calling
nfs41_open_expired() when a TEST_STATEID returns NFS4ERR_DELEG_REVOKED.
