Hi Jens, This patch series improves write performance for zoned UFS devices. Please consider these patches for the next merge window. Thank you, Bart. Changes compared to v2: - Renamed the request queue flag for disabling zone write locking. - Introduced a new request flag for disabling zone write locking. - Modified the mq-deadline scheduler such that zone write locking is only disabled if both flags are set. - Added an F2FS patch that sets the request flag for disabling zone write locking. - Only disable zone write locking in the UFS driver if auto-hibernation is disabled. Changes compared to v1: - Left out the patches that are already upstream. - Switched the approach in patch "scsi: Retry unaligned zoned writes" from retrying immediately to sending unaligned write commands to the SCSI error handler.
