blk-cgroup works on only on live disks and "file system" I/O from bios.
This all the information should be in the gendisk, and not the
request_queue that also exists for pure passthrough request based
devices.

Can't blk-throttle be used w/ bio based ones tho? I always thought that was
the reason why we didn't move it into rq-qos framework.

Thanks.
