[PATCHv4 0/4] block and nvme passthrough error handling

[Keith Busch]

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()
