From 8ca017c8cee3aa6a37ddf1db7fd04c54536a0ef0 Mon Sep 17 00:00:00 2001 From: Scott Mayhew Date: Mon, 6 May 2019 11:59:05 -0400 Subject: NFSv4: don't mark all open state for recovery when handling recallable state revoked flag 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.
