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
