Date: Fri, 10 Oct 2025 17:14:25 +0800 [thread overview]

From: Yu Kuai <yukuai3@huawei.com>
Changes in v2:
- add patch 2 to delay freeing policy data, otherwise patch 3 is not
safe;
- add patch 13-19 to cleanup blkcg configuration apis;
patch 1-8 is prep patches to make sure queue_lock is not nested under
rcu and other spinlocks in blk-cgroup;
patch 9 convert blk-cgroup to use blkcg_mutex to protect blkgs;
patch 10,11 are follow cleanups;
patch 12 fix deadlock in blk-throttle;
patch 13-19 cleanup blkcg configuration helpers;
Yu Kuai (19):
blk-cgroup: protect iterating blkgs with blkcg->lock in
blkcg_print_stat()
blk-cgroup: delay freeing policy data after rcu grace period
blk-cgroup: don't nest queue_lock under rcu in blkcg_print_blkgs()
blk-cgroup: don't nest queue_lock under rcu in blkg_lookup_create()
