Subject: linux-next: manual merge of the md tree with the device-mapper tree

Hi Neil,

Today's linux-next merge of the md tree got a conflict in
drivers/md/dm-raid.c between commit 43390ddd7f36 ("The dm-raid code
currently fails to create a RAID array if any of the") from the
device-mapper tree and commit 760e35d7e573 ("md: tidy up rdev_for_each
usage") from the md tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.
