Version 1.02.68 -
==================================
+ Add 'blkdevname' and 'blkdevs_used' field to dmsetup info -c -o.
+ Add 'blkdevname' option to dmsetup ls --tree to see block device names.
+ Add '-o options' to dmsetup deps and ls to select device name type on output.
Add dm_device_get_name to get map name or block device name for given devno.
Remove empty devices when clearing left-over inactive tables in deptree.
Add dm_uuid_prefix/dm_set_uuid_prefix to override hard-coded LVM- prefix.
