Subject: [PATCH v2] NFSv4: don't mark all open state for recovery when handling recallable state revoked flag
Date: Mon, 6 May 2019 11:59:05 -0400 [thread overview]
Message-ID: <20190506155905.16152-1-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.
