[PATCH] knfsd: Fix bug in recent lockd patches that can cause reclaim to fail
When an nfs server shuts down, lockd needs to release all the locks even
though the client still holds them.
It should therefore not 'unmonitor' the clients, so that the files in nfs/sm
will still be there when the nfs server restarts, so that those clients will
be told to reclaim their locks.
However the hosts are fully unmonitored, so statd may well remove the files.
lockd has a test for 'sm_sticky' and avoid the unmonitor call if it is set,
but it is currently not set.
So set it when tearing down lockd.
