Subject: [PATCH 2/3] Do not read DDF RAID UUID from udev
The UUID we get from udev isn't the array UUID, we need to get
that using libblockdev.

Subject: [PATCH 3/3] Do not crash when a disk populator doesn't return kwargs
This happens when trying to use Blivet on a system with a BIOS
RAID without dmraid installed. Because we don't fully support
BIOS RAIDs using MD the MDBiosRaidDevicePopulator helper fails
to get kwargs for the BIOS RAID "disk" and populate fails.
