Stan and I were chatting about the excess recovery notifications that we
get from the current ODLM lock module.  These happen with the current
deadman lock design when a client (filesystem) mounts or unmounts on
another node.

Without going into detail ... I'm wondering if we can use the *lock
value blocks* of the deadman locks to communicate whether:

1)  A client has cleanly unmounted (no recovery needed)

2)  A new client has mounted (no recovery needed after first-to-mount)

3)  A node died (recovery needed)

Opinions are mine, not Intel's
