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 scsi: remove ->change_queue_type method
