Here is the branch, btw: http://git.kernel.dk/cgit/linux-block/log/?h=for-4.11/blk-mq-legacy-sched if you want to look at it or test it.

Should be ready for testing, I've successfully run various IO tests on deadline and CFQ with null_blk loaded with queue_mode=2 submit_queues=1 use_sched=1. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
