To: linux-block; +Cc: Bruno Goncalves, skt-results-master
So bisecting shows it was introduced from this commit, and it's 100%
reproduced with blktests block/001 on the ppc64le.
commit 8e141f9eb803e209714a80aa6ec073893f94c526 (HEAD)
Author: Christoph Hellwig <hch@lst.de>
Date: Wed Sep 29 09:12:40 2021 +0200
block: drain file system I/O on del_gendisk
Instead of delaying draining of file system I/O related items like the
blk-qos queues, the integrity read workqueue and timeouts only when the
request_queue is removed, do that when del_gendisk is called. This is
important for SCSI where the upper level drivers that control the gendisk
are separate entities, and the disk can be freed much earlier than the
request_queue, or can even be unbound without tearing down the queue.

Hi Yi,
can you try the patch below? This changes the teardown code to not
re-enable writeback tracking when we're shutting the queue down, which
is what I suspect is on the ->callbacks list.
