Hi, This series of patches enables dmsetup to control which types of devices are listed. For example, "dmsetup info -c -o name --filter 'parents_count == 0'" will display top-level dm devices and "dmsetup info -c --filter 'uuid !~ /^LVM/'" will display dm devices which are not LVM2 volumes. As the feature is implemented in libdevmapper, LVM2 is easily made to use it, too. The patch will be posted to lvm-devel.
