Title:
  umount confused by device names with '-' in them

Status in “util-linux” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: util-linux

  Device mapper devices, such as LVM and dmraid devices, have a '-' in
  the name.  If you mount /dev/dm-7 somewhere, then try to umount
  /dev/dm-7, it fails saying that is not mounted.  This seems to be
  because umount is confused by the '-' character and so fails to
  translate the device name to the mount point when calling umount().
  Manually editing /etc/mtab and removing the '-' allows umount /dev/dm7
  to succeed.
