Can you try the below fix? Should be more palatable than the previous
one. Brian, maybe you can take a look at the IRQ issue mentioned above?

Given the patch from Brian fixed the lockdep warning, do you still want
me to try and test this one?

Nope, we don't have to do that. I'd much rather just add a WARN_ON()
or similar to make sure we catch buggy users earlier. scsi_run_queue()
needs a

WARN_ON(in_interrupt());

but it might be better to put that in __blk_mq_run_hw_queue().
