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

[Mohamed Khalfella]

The patch in v2 converted set->tag_list_lock to a rwsemaphore. It was
pointed out this could result in a different kind of deadlock. This
patch uses RCU to protect set->tag_list when accessed from [un]quiesce
code.

v2 - https://lore.kernel.org/all/20251117202414.4071380-1-mkhalfella@xxxxxxxxxxxxxxx/
