[dm-devel] [PATCH 2/3] dm core: export dm_disk to allow for dm-raid to pass it on to the MD raid0 personality

[heinzm at redhat.com]

From: Heinz Mauelshagen <heinzm at redhat.com>

This patch is a prerequisite for dm-raid "raid0" support to allow
dm-raid to set rs->md.gendisk, which is required by the MD RAID0
pesonality to set disk stacking limits.
