From: Yu Kuai <yukuai3@huawei.com>

Changes in v2:
 - add patch 1;

The idea is that ioprio doesn't need to access blkg, all it needs is
blkcg, hence blk_register_policy() is enough, and blk_activate_policy()
is not needed.

Yu Kuai (3):
  blk-cgroup: check for pd_(alloc|free)_fn in blkcg_activate_policy()
  blk-ioprio: remove ioprio_blkcg_from_bio()
  blk-ioprio: remove per-disk structure
