# losetup -a
/dev/loop0: [fe04]:65738 (/var/lib/vm/0/hda1.img)
/dev/loop1: [fe04]:65752 (/var/lib/vm/0/hda3.img)
/dev/loop10: [fe04]:17097 (/etc/vm/images/1.3r5136/hda2.img)

So "[fe04]" in "losetup -a" output is device id and the number after that is
the inode number.

# rpm -q losetup
losetup-2.13-0.pre7.2.i686

So it cames from util-linux version 2.13pre7.
