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.
