From: Heinz Mauelshagen <heinzm at redhat.com>

This patchset of 3 adds access to the MD RAID0 personality to dm-raid
(in addition to the already supported raid1/10/4/5/6 personalities)
to enable single zone striping.

The added functionality is the first step to allow full support
of MD kernel functionality via dm-raid and to eventually replace
the dm "striped" target altogether. Adding shrink/takeover and
reshape functionality to dm-raid is subject to future patches.
