Pull SCSI updates from James Bottomley: "This series consists of the usual driver updates (ufs, qla2xxx, target, smartpqi, lpfc, mpt3sas). The core change causing the most churn was replacing the command request field request with a macro, allowing us to offset map to it and remove the redundant field; the same was also done for the tag field. The most impactful change is the final removal of scsi_ioctl, which has been deprecated for over a decade" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (293 commits) scsi: ufs: Fix ufshcd_request_sense_async() for Samsung KLUFG8RHDA-B2D1 scsi: ufs: ufs-exynos: Fix static checker warning scsi: mpt3sas: Use the proper SCSI midlayer interfaces for PI scsi: lpfc: Use the proper SCSI midlayer interfaces for PI scsi: lpfc: Copyright updates for 14.0.0.1 patches scsi: lpfc: Update lpfc version to 14.0.0.1 scsi: lpfc: Add bsg support for retrieving adapter cmf data scsi: lpfc: Add cmf_info sysfs entry scsi: lpfc: Add debugfs support for cm framework buffers scsi: lpfc: Add support for maintaining the cm statistics buffer scsi: lpfc: Add rx monitoring statistics scsi: lpfc: Add support for the CM framework scsi: lpfc: Add cmfsync WQE support scsi: lpfc: Add support for cm enablement buffer scsi: lpfc: Add cm statistics buffer support scsi: lpfc: Add EDC ELS support scsi: lpfc: Expand FPIN and RDF receive logging scsi: lpfc: Add MIB feature enablement support scsi: lpfc: Add SET_HOST_DATA mbox cmd to pass date/time info to firmware scsi: fc: Add EDC ELS definition ...
