[PATCH] knfsd: call lockd_down when closing a socket via a write to nfsd/portlist
The refcount that nfsd holds on lockd is based on the number of open sockets. So when we close a socket, we should decrement the ref (with lockd_down). Currently when a socket is closed via writing to the portlist file, that doesn't happen. So: make sure we get an error return if the socket that was requested does is not found, and call lockd_down if it was. Cc: "J.
