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
