Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "This consists of the usual driver updates (ufs, smartpqi, lpfc, target, megaraid_sas, hisi_sas, qla2xxx) and minor updates and bug fixes. Notable core changes are the removal of scsi->tag which caused some churn in obsolete drivers and a sweep through all drivers to call scsi_done() directly instead of scsi->done() which removes a pointer indirection from the hot path and a move to register core sysfs files earlier, which means they're available to KOBJ_ADD processing, which necessitates switching all drivers to using attribute groups" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (279 commits) scsi: lpfc: Update lpfc version to 14.0.0.3 scsi: lpfc: Allow fabric node recovery if recovery is in progress before devloss scsi: lpfc: Fix link down processing to address NULL pointer dereference scsi: lpfc: Allow PLOGI retry if previous PLOGI was aborted scsi: lpfc: Fix use-after-free in lpfc_unreg_rpi() routine scsi: lpfc: Correct sysfs reporting of loop support after SFP status change scsi: lpfc: Wait for successful restart of SLI3 adapter during host sg_reset scsi: lpfc: Revert LOG_TRACE_EVENT back to LOG_INIT prior to driver_resource_setup() scsi: ufs: ufshcd-pltfrm: Fix memory leak due to probe defer scsi: ufs: mediatek: Avoid sched_clock() misuse scsi: mpt3sas: Make mpt3sas_dev_attrs static scsi: scsi_transport_sas: Add 22.5 Gbps link rate definitions scsi: target: core: Stop using bdevname() scsi: aha1542: Use memcpy_{from,to}_bvec() scsi: sr: Add error handling support for add_disk() scsi: sd: Add error handling support for add_disk() scsi: target: Perform ALUA group changes in one step scsi: target: Replace lun_tg_pt_gp_lock with rcu in I/O path scsi: target: Fix alua_tg_pt_gps_count tracking scsi: target: Fix ordered tag handling ...
