Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI update from James Bottomley:
"This is a much shorter set of patches that were on the go but didn't
make it in to the early pull request for the merge window. It's
really a set of bug fixes plus some final cleanup work on the new tag
queue API"
* tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
storvsc: ring buffer failures may result in I/O freeze
ipr: set scsi_level correctly for disk arrays
ipr: add support for async scanning to speed up boot
scsi_debug: fix missing "break;" in SDEBUG_UA_CAPACITY_CHANGED case
scsi_debug: take sdebug_host_list_lock when changing capacity
scsi_debug: improve driver description in Kconfig
scsi_debug: fix compare and write errors
qla2xxx: fix race in handling rport deletion during recovery causes panic
scsi: blacklist RSOC for Microsoft iSCSI target devices
scsi: fix random memory corruption with scsi-mq + T10 PI
Revert "[SCSI] mpt3sas: Remove phys on topology change"
Revert "[SCSI] mpt2sas: Remove phys on topology change."
esas2r: Correct typos of "validate" in a comment
fc: FCP_PTA_SIMPLE is 0
ibmvfc: remove unused tag variable
scsi: remove MSG_*_TAG defines
scsi: remove scsi_set_tag_type
scsi: remove scsi_get_tag_type
scsi: never drop to untagged mode during queue ramp down
