I guess, fixing the umount is needed and it is easy. I will send a fix.

The kernel side is not as easy! The NFS4 mounts the root first then the
exported path using subtree_mount() which seem to remove the actual
string and replace it with a real path. We can save the devname
somewhere and get it into nfs_show_devname(), but I am not sure that
works.

Thanks, Malahal.
