>Description:
A user, in a directory of /u1/home/gregp/mnt, ran this command:

	mount_procfs /proc ../blah


"mount" shows:

procfs on ../blah type procfs (local, nodev, nosuid)

and this cannot be unmounted.  I have tried the following:

root@kechara# cd /
root@kechara# umount -t procfs -a
umount: /blah: not currently mounted

root@kechara# cd /home/gregp/mnt/
root@kechara# umount -t procfs -a
umount: /u1/home/gregp/blah: not currently mounted

When I wrote a small C program to issue
	unmount("/home/gregp/blah", 0);
it was unmounted.

>How-To-Repeat:
See above.
>Fix:
Perhaps the -f flag should not bother checking the list of filesystems
or something...
