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
