A patch for util-linux that fixes umount's behavior when dealing with
volumes remounted using --bind. When looking up data in /etc/mtab
in order to unmount a volume, any mnt_dir match should take priority
because unmounting by fsname is obsolete. Otherwise unmounting a volume
that was also mounted with --bind will misbehave (Parent's mnt_dir is
child's mnt_fsname).
My research interests include free and open source software, system security, and network security.
