NeilBrown 729a18663a md/raid5: don't complete make_request on barrier until writes are scheduled ... The post-barrier-flush is sent by md as soon as make_request on the barrier write completes. For raid5, the data might not be in the per-device queues yet. So for barrier requests, wait for any pre-reading to be done so that the request will be in the per-device queues. We use the 'preread_active' count to check that nothing is still in the preread phase, and delay the decrement of this count until after write requests have been submitted to the underlying devices.
