Subject: [PATCHv3 0/4] block and nvme passthrough error handling
Date: Fri, 21 May 2021 13:21:41 -0700	[thread overview]
Message-ID: <20210521202145.3674904-1-kbusch@kernel.org> (raw)

This series gets blk_execute_rq() to process polled requests and return
queueing errors so the caller may know if their request wasn't
dispatched.

Changes since v2:

  Dropped patch 5 (ioctl polling flag) since there is currently no real
  use case.

  Move blk_execute_rq's poll handling to a small helper function
  (patch 1)

  Return blk_status_t instead of errno (patch 3)

  Removed "extern" header declaration, and named the parameters (patch 3)

  Initialize nvme status to 0 (patch 4)

  Add helper function for blk_status_t to nvme passthrough return code
  (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()
