Subject: [PATCH 0/6] loop: cleanup charging io to mem/blkcg
Date: Mon,  5 Jul 2021 18:26:01 +0800	[thread overview]
Message-ID: <20210705102607.127810-1-ming.lei@redhat.com> (raw)

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
