Subject: [PATCH v4 0/1] block: Use RCU in blk_mq_[un]quiesce_tagset() instead of set->tag_list_lock

Changes from v3:
- Fixed typos in commit message.
- Updated stacktrace in commit message with one taken from recent kernel.
- Added Fixes: tag to commit message.
- Deleted synchronize_rcu() (added in v3) and pre-existing
  INIT_LIST_HEAD(&q->tag_set_list) call in blk_mq_del_queue_tag_set().
- Updated the commit message to mention why it is safe to delete
  INIT_LIST_HEAD(&q->tag_set_list) in blk_mq_del_queue_tag_set().

v3 - https://lore.kernel.org/all/20251204181212.1484066-1-mkhalfella@purestorage.com/
