rq_qos_exit is already called in blk_cleanup_queue, and the blk-mq
pollig doesn't even use the qos framework. So I'm not sure what this
is supposed to help.

The crash is likely triggered by nbd. wb_timer_fn+0x56 is block/blk-wbt.c: 237
like in the syzbot reported crash. That line was just recently touched,
so i wonder whether that's related?

Yes. I'll try to reproduce it outside of CI and test the patch set. Thanks!

I tested it without your patchset and it crashed around every second
try. With that patchset, i wasn't able to reproduce it.
Thanks!
