Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Eight bug fixes, one spelling update and one tracepoint addition.
The most serious is probably the mptsas write same fix because it
means anyone using these controllers sees errors when modern
filesystems try to issue discards"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: target: fix crash with iscsi target and dvd
scsi: sd_zbc: Avoid that resetting a zone fails sporadically
scsi: sd: Defer spinning up drive while SANITIZE is in progress
scsi: megaraid_sas: Do not log an error if FW successfully initializes.
scsi: ufs: add trace event for ufs upiu
scsi: core: remove reference to scsi_show_extd_sense()
scsi: mptsas: Disable WRITE SAME
scsi: fnic: fix spelling mistake in fnic stats "Abord" -> "Abort"
scsi: scsi_debug: IMMED related delay adjustments
scsi: iscsi: respond to netlink with unicast when appropriate
