Ok, thanks for testing.  Can you try the patch below?  It fixes a
clear problem which was partially papered over before the commit
you bisected to, although it can't explain why blk-mq still works.

Still bad luck. :-(

BTW, I'm using the first "bad" commit (scsi: allocate scsi_cmnd structures as
part of struct request) + the 2 patches you provided today.

I suppose I don't need to test the 2 patches on the latest linux-next repo.

I'd love a test on that repo actually.  We had a few other for sense
handling since then I think.
