Trond Myklebust 032a7d5ff5 nfsd: Ensure knfsd shuts down when the "nfsd" pseudofs is unmounted ...

commit c6c7f2a84da459bcc3714044e74a9cb66de31039 upstream.

In order to ensure that knfsd threads don't linger once the nfsd
pseudofs is unmounted (e.g. when the container is killed) we let
nfsd_umount() shut down those threads and wait for them to exit.

This also should ensure that we don't need to do a kernel mount of
the pseudofs, since the thread lifetime is now limited by the
lifetime of the filesystem.
