hi neil-

it looks like you have the most expertise in this area, so you are the
lucky victim today.

our filer sends NLM GRANTED callbacks back to clients using AUTH_NULL
authentication.  Linux clients always seem to reject these callbacks.

parsing through fs/lockd and net/sunrpc, i see a comment that indicates
that AUTH_NULL RPC requests are subject to IP access control (a la
/etc/exports).  theoretically, if lockd doesn't register the filer in
the ip_map cache, then all the filer's callbacks will be rejected,
right?
