Subject: [PATCH 4.9 023/164] dm raid: select the Kconfig option CONFIG_MD_RAID0

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mikulas Patocka <mpatocka@...hat.com>

commit 7b81ef8b14f80033e4a4168d199a0f5fd79b9426 upstream.

Since the commit 0cf4503174c1 ("dm raid: add support for the MD RAID0
personality"), the dm-raid subsystem can activate a RAID-0 array.
Therefore, add MD_RAID0 to the dependencies of DM_RAID, so that MD_RAID0
will be selected when DM_RAID is selected.

Fixes: 0cf4503174c1 ("dm raid: add support for the MD RAID0 personality")
