This patch series converts the remaining drivers to blk-mq. The ones that support dual paths (like SCSI and DM) have the non-mq path removed. At the end, legacy IO code and schedulers are killed off. This patch series is on top of my for-linus branch. It can also be bound in my mq-conversions branch.
