From: Niklas Cassel <niklas.cassel@xxxxxxx> Recently, there were some extra "dummy" data added into mq-deadline rq->elv.priv, that was there for the solve purpose of working around shortcomings in blk-mq (which called the scheduler callbacks even for requests that bypassed the scheduler). Fix blk-mq to behave in a more sane way with regards to scheduler callback triggering, and remove the now unneeded rq->elv.priv magic. BFQ should be able to perform a similar cleanup, and should be able to drop this comment from the code: https://github.com/torvalds/linux/blob/master/block/bfq-iosched.c#L6456-L6462 Considering that I'm quite unfamiliar with the BFQ code, I'd rather someone who is a bit more familiar with BFQ performs that cleanup.
