[PATCHv3,0/4] zoned block device specific errors

Message

Keith Busch Sept. 17, 2020, 11:18 p.m. UTC

Zone block devices may have some limits that require special handling.
This series provides a way for drivers to notify of these conditions.

v2->v3:

  Split status for max open vs max active errors (Christoph)

  Include scsi use for the new status (Damien)

  Update documentation for the new status inline with the request_queue
  properties they relate to

Damien Le Moal (2):
  scsi: update additional sense codes list
  scsi: handle zone resources errors

Keith Busch (2):
  block: add zone specific block statuses
  nvme: translate zone resource errors

We will also need to send an update for nullblk on top of Miklas patch that adds
MAR/MOR emulation, to have everything in sync. But Jens has not pulled that one
in yet I think.

Jens,

We could add Niklas patch, modified, to this series too. Or do you prefer an
incremental update for it ?

This looks good to me. I already queued patch 3 so please send a v4 with
that patch removed. The rest should go through Jens' tree.
