John,

As I mentioned in the thread that spawned from this, we actually can't
expose multiple hw queues at the moment. And, if we did, we find a
performance drop due to having to go back to manage this IPTT
internally.

So how to handle? We're going to continue to work towards exposing
multiple queues to upper layer, but for the moment I think patch 6/7 is
a good change.

Thanks for the discussion. That's exactly what I was looking for.

Applied to 4.20/scsi-queue.


Great, thanks.
