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 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.

Bart Van Assche (5):
  block: Introduce a request queue flag for pipelining zoned writes
  block/mq-deadline: Only use zone locking if necessary
  block/null_blk: Add support for pipelining zoned writes
  scsi: Retry unaligned zoned writes
  scsi: ufs: Enable zoned write pipelining
