Benjamin Coddington a9b8d90f87 NFSv4: fairly test all delegations on a SEQ4_ revocation ... When the client is required to use TEST_STATEID to discover which delegation(s) have been revoked, it may continually test delegations at the head of the list if the server continues to be unsatisfied and send SEQ4_STATUS_RECALLABLE_STATE_REVOKED. For a large number of delegations this behavior is prone to live-lock because the client may never be able to test and free revoked state at the end of the list since the SEQ4_STATUS_RECALLABLE_STATE_REVOKED will cause us to flag delegations at the head of the list to be tested. This problem is further exacerbated by the state manager's willingness to be scheduled out on a busy system while testing the list of delegations. Keep a generation counter for each attempt to test all delegations, and skip delegations that have already been tested in the current pass.
