We need to fix up a few more spots for IOPOLL. 1/7 adds locking
and is intended to be backported, all 2-5 prepare the code and 5/6,
fixes the problem and 7/7 reverts the first patch for-next. 

Pavel Begunkov (7):
  io_uring: add completion locking for iopoll
  io_uring: hold locks for io_req_complete_failed
  io_uring: use io_req_task_complete() in timeout
  io_uring: remove io_req_tw_post_queue
  io_uring: inline __io_req_complete_put()
  io_uring: iopoll protect complete_post
  io_uring: remove iopoll spinlock
