Ok.

All right, that maks sense.The reported oopses seem to be about block
requests. Some of them were scsi in particular.

Let's bring in Jens and the SCSI people. Maybe that host reference
counting? There's quite a lot of "move freeing around" in that late
scsi pull, even if it was touted as "mostly small bug fixes and
trivial updates".

Here's the two threads:

  https://lore.kernel.org/all/20220814043906.xkmhmnp23bqjzz4s@xxxxxxxxxxxxxxxxxx/

but I guess I'll do an -rc1 regardless of this, because I need to
close the merge window.
