I discovered the problem. In late October 2007, the exportfs
interface was changed [1], and cifs was not updated during the
update. (export.c was last touched non-trivially in early October)

cifs currently is missing the one mandatory method fh_to_dentry in
the export_operations structure, so the exportfs code rejects it as
an exportable filesystem.

I dunno if anyone's planning to fix this, I think I'll have a go
just pointing it at generic_fh_to_dentry (as this seems to be the
intended behaviour under the old API) and see if that works or if
it sets our machines on fire.

Of course Pacman didn't influence us as kids. If it did,
we'd be running around in darkened rooms, popping pills and
listening to repetitive music.
