Example below: mproot-part1 (dev 253:3, a partition of mp device 253:2) isn't listed as a dependency of any device. Likewise each listed LVM volume isn't listed as a dependency of any device; example- rootvg-tmp 253:10 Sure, but a /dev/sda2 won't show up in dmsetup output anywhere. That's kind of my point.
