Hello, Below issue was triggered with ( v6.0.15-996-g988abd970566), pls help check it

There isn't commit 988abd970566 in linux-6.0.y, so I guess the above build must integrate other patches not in 6.0.y

From the source code in cki build[1], looks commit 80bd4a7aab4c ("blk-mq: move the srcu_struct used for quiescing to the tagset") is included, but commit 8537380bb988 ("blk-mq: skip non-mq queues in blk_mq_quiesce_queue") is missed, that is why this panic is triggered.

I just found that patch of blk-mq-move-the-srcu_struct-used-for-quiescing-to-th.patch is queued in stable-queue/queue-6.0, but that patch depends on commit 8537380bb988 ("blk-mq: skip non-mq queues in blk_mq_quiesce_queue"). which needs to be added to queue-6.0 too.

Thanks, Ming
