There are no block drivers in the upstream kernel that set
QUEUE_FLAG_SAME_FORCE. An explanation is missing from the patch
description why this flag is set from the UFS driver instead of by
writing the value "2" into /sys/class/block/$bdev/queue/rq_affinity.
Additionally, an explanation is missing why QUEUE_FLAG_SAME_FORCE is
set but QUEUE_FLAG_SAME_COMP not.
