[PATCHv2 0/5] block and nvme passthrough error handling

[Keith Busch]

v1 -> v2:

  Unify nvme's polled and non-polled requests by pushing that logic to
  the generic block layer.

  Include the ioctl and passthrough users for getting the error status
  from the passthrough execution.

  Added nvme patch allowing a user to specify a polled ioctl request.

Keith Busch (5):
  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()
  nvme: allow user passthrough commands to poll
