I've traced this to the following merge commit:

dave@atlas:~/linux/linux$ git bisect good
ca7ce08d6a063e0ccb91dc57f9bc213120d0d1a7 is the first bad commit
commit ca7ce08d6a063e0ccb91dc57f9bc213120d0d1a7

     Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

     Pull SCSI updates from James Bottomley:
      "Updates to the usual drivers (ufs, pm80xx, libata-scsi, smartpqi,
       lpfc, qla2xxx).

       We have a couple of major core changes impacting other systems:

        - Command Duration Limits, which spills into block and ATA

        - block level Persistent Reservation Operations, which touches block,
          nvme, target and dm

       Both of these are added with merge commits containing a cover letter
       explaining what's going on"
