NFSv4 minor version 0 servers return an error code, NFS4ERR_LEASE_MOVED, to signal LEASE_MOVED. This error causes the whole compound to fail. Minor version 1+ servers set a bit flag in the reply to a compound's SEQUENCE operation to signal LEASE_MOVED. The compound succeeds. After the server sets one of the sr_status_flags in a typical compound operation, nfs41_sequence_done() initiates standard lease recovery. A stand-alone SEQUENCE operation is performed to discover what recovery is needed. If the LEASE_MOVED status flag is set in this SEQUENCE operation, our client kick offs LEASE_MOVED recovery.
