  Hasn't all of this been moot'ified by the changes w.r.t. PR 441,
basically, umount -R?  On a system running a few months' old
-current:

12:03am 20# cd /tmp; mkdir a
12:03am 21# mount | grep mnt
12:03am 22# mount_null /mnt ./a
12:03am 23# mount | grep mnt
/mnt on ./a type null (local)
12:03am 24# umount a
umount: /tmp/a: not currently mounted
12:04am 25# mount | grep mnt
/mnt on ./a type null (local)
12:04am 26# umount ./a
umount: /tmp/a: not currently mounted
12:04am 27# mount | grep mnt
/mnt on ./a type null (local)
12:04am 28# umount -R ./a
Segmentation fault
12:04am 29# mount | grep mnt
12:04am 30# 

  Similarly, for the symlink case:
12:04am 30# ln -s /tmp/a c
12:06am 31# mount_null /mnt /tmp/c
12:06am 32# mount | grep mnt
/mnt on /tmp/c type null (local)
12:06am 33# umount /tmp/c
umount: /tmp/a: not currently mounted
12:06am 34# mount | grep mnt
/mnt on /tmp/c type null (local)
12:06am 35# umount -R /tmp/c
Segmentation fault
12:06am 36# mount | grep mnt
12:06am 37# 

  I don't remember what the seg fault is from, or if it has been
fixed in -current, but -R seems to do the trick for me.
