Yeah, I'm getting to this now. Two more things I wanna do are

- Moving stats and configurations to blkg policies instead of putting
them in blk-cgroup.c and then pipe to cgroup policies. This will
require updates to cgroup to allow live removal / addition of cgroup
files on existing cgroup directories. Should be doable but I'm a
bit skeptical cgroup is implementing proper sever mechanism on files
and if not we're gonna have to implement that first.

- Make enabled policies per-queue.

Thanks.
