nd.mnt is what? NULL? There's your oops.
Grab fs/nfsctl.c::do_open() and s/nfsd/proc/g in there. FWIW, it's probably
better off in libfs.c with fs type as argument... For now, just copy it -
it's trivial and small enough; when I move the sucker to libfs, we'll
switch to that. And lose that deactivate_super(), obviously - you won't
be touching superblock anymore.
