Hello Guys,

Cleanup charging io to mem/blkcg a bit:

- avoid to store blkcg_css/memcg_css in loop_cmd, and store blkcg_css in
loop_worker instead

- avoid to acquire ->lo_work_lock in IO path

- simplify blkcg_css query via xarray

- other misc cleanup



Ming Lei (6):
  loop: clean up blkcg association
  loop: conver timer for monitoring idle worker into dwork
  loop: add __loop_free_idle_workers() for covering freeing workers in
    clearing FD
  loop: improve loop_process_work
  loop: use xarray to store workers
  loop: don't add worker into idle list
