adds a check for sequence flag SEQ4_STATUS_RESTART_RECLAIM_NEEDED in nfs41_recover_sequence_flags(). if other _STATE_REVOKED flags are set, call nfs41_client_state_revoked() as normal but follow it up with a RECLAIM_COMPLETE. otherwise, reclaim all locks with nfs41_recover_client_state(). like other callers of nfs41_recover_client_state(), we need to handle BADSESSION errors because the recovery operations are sent with try_recovery=FALSE. because this logic is similar to our default NFS4ERR_BADSESSION handling, i moved the common code into a new nfs41_recover_session() function in recovery.c Signed-off-by: Casey Bodley <cbodley@citi.umich.edu>
