Subject: [PATCH] [PATCH] device-mapper: dm-raid1: Limit bios to size of mirror
 region

Set the target's split_io field when building a dm-mirror device so
incoming bios won't span the mirror's internal regions.  Without this,
regions can be accessed while not holding correct locks and data corruption
is possible.
