Mikulas Patocka 1e5554c842 dm snapshot: iterate origin and cow devices ... Iterate both origin and snapshot devices iterate_devices method should call the callback for all the devices where the bio may be remapped. Thus, snapshot_iterate_devices should call the callback for both snapshot and origin underlying devices because it remaps some bios to the snapshot and some to the origin. snapshot_iterate_devices called the callback only for the origin device. This led to badly calculated device limits if snapshot and origin were placed on different types of disks.
