[PATCH] knfsd: Correctly handle error condition from lockd_up
If lockd_up fails - what should we expect? Do we have to later call
lockd_down?
Well the nfs client thinks "no", the nfs server thinks "yes". lockd thinks
"yes".
The only answer that really makes sense is "no" !!
So:
Make lockd_up only increment nlmsvc_users on success.
Make nfsd handle errors from lockd_up properly.
Make sure lockd_up(0) never fails when lockd is running
so that the 'reclaimer' call to lockd_up doesn't need to
be error checked.
