Subject: [PATCH 03/24] create cleanup helper svc_msnfs()
I'm going to be modifying nfsd_rename() shortly to support
read-only bind mounts. This #ifdef is around the area I'm
patching, and it starts to get really ugly if I just try
to add my new code by itself. Using this little helper
makes things a lot cleaner to use.
