Subject: [PATCHv4 0/4] block and nvme passthrough error handling
Date: Thu, 10 Jun 2021 14:44:33 -0700	[thread overview]
Message-ID: <20210610214437.641245-1-kbusch@kernel.org> (raw)

This series has blk_execute_rq() return queueing errors so the caller
may know if their request wasn't dispatched, and adds polled hctx
support.

Chances since v3:

  Added recieved "Reviewed-by:" tags.

  Retain the REQ_HIPRI flag for nvme polled passthrough requests
  (patch 2)

  Combined nvme request dispatch with the status decoding into single
  function (patch 4)

Keith Busch (4):
  block: support polling through blk_execute_rq
  nvme: use blk_execute_rq() for passthrough commands
  block: return errors from blk_execute_rq()
  nvme: use return value from blk_execute_rq()
