Subject: [PATCH V3 0/7] loop: cleanup charging io to mem/blkcg
Date: Fri,  6 Aug 2021 10:34:16 +0800	[thread overview]
Message-ID: <20210806023423.131060-1-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

V3:
	- one patch style change in 7/7
	- rebase patch 4/7 against for-5.15/block
	- add acked-by tag

V2:
	- add helper of memcg_get_e_css
	- cleanup #ifdef
	- improve the last patch, as discussed with Dan Schatzberg


Ming Lei (7):
  mm: memcontrol: add helper of memcg_get_e_css
  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
