1. "sm-notify" callout name
2. monitored client name as in the SM_NOTIFY request
3. IP of the sender of the SM_NOITFY request.
4. state value in the SM_NOTIFY request
This new interface can be used by different HA-NFS product
in its specific configuration and environment to
recover from the client crash and stale lock scenarios.
