Should these go back farther than 4.12? Looks like they apply cleanly to 4.9, didn't look older than that...I met prerequisites at 4.11...FWIW, I took/modified 2d0364c8c1a9. Dunno if the suspend regression exists in 4.11 though, without which you'll likely want nothing.
It does exist, the only change here is that we default people to scsi-mq in 4.12+. Honestly, nobody complained since we've had scsi-mq, so I could pivot both ways on whether we really need the changes in earlier versions or not. -- Jens Axboe
