Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley: "Updates to the usual drivers (ufs, pm80xx, libata-scsi, smartpqi, lpfc, qla2xxx). We have a couple of major core changes impacting other systems: - Command Duration Limits, which spills into block and ATA - block level Persistent Reservation Operations, which touches block, nvme, target and dm Both of these are added with merge commits containing a cover letter explaining what's going on" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (187 commits) scsi: core: Improve warning message in scsi_device_block() scsi: core: Replace scsi_target_block() with scsi_block_targets() scsi: core: Don't wait for quiesce in scsi_device_block() scsi: core: Don't wait for quiesce in scsi_stop_queue() scsi: core: Merge scsi_internal_device_block() and device_block() scsi: sg: Increase number of devices scsi: bsg: Increase number of devices scsi: qla2xxx: Remove unused nvme_ls_waitq wait queue scsi: ufs: ufs-pci: Add support for Intel Arrow Lake scsi: sd: sd_zbc: Use PAGE_SECTORS_SHIFT scsi: ufs: wb: Add explicit flush_threshold sysfs attribute scsi: ufs: ufs-qcom: Switch to the new ICE API scsi: ufs: dt-bindings: qcom: Add ICE phandle scsi: ufs: ufs-mediatek: Set UFSHCD_QUIRK_MCQ_BROKEN_RTC quirk scsi: ufs: ufs-mediatek: Set UFSHCD_QUIRK_MCQ_BROKEN_INTR quirk scsi: ufs: core: Add host quirk UFSHCD_QUIRK_MCQ_BROKEN_RTC scsi: ufs: core: Add host quirk UFSHCD_QUIRK_MCQ_BROKEN_INTR scsi: ufs: core: Remove dedicated hwq for dev command scsi: ufs: core: mcq: Fix the incorrect OCS value for the device command scsi: ufs: dt-bindings: samsung,exynos: Drop unneeded quotes ...
