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"
