Testing this is pretty hard.  You export a filesystem, then cd somewhere
deep into a directory hiearchy in there.  Then unexport the filesystem
and unmount on the server.  mount it back on the server, export it again
and do something with a file from the directory you've cd into before
the unmount.  Make sure you have a printk in your get_parent method
to make sure you're really hitting it.

Btw, I think it would be nicer to opencode the .. lookup in get_parent
instead of changing udf_find_entry.  The lookup for .. is not needed
by anything else, and get_parent only looks for it so it's a natural
place to opencode it there.
