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
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
