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/20220814212610.GA3690074@roeck-us.net/ https://lore.kernel.org/all/20220814043906.xkmhmnp23bqjzz4s@awork3.anarazel.de/ but I guess I'll do an -rc1 regardless of this, because I need to close the merge window.
