[PATCH v3 0/3] next work propagation

[Pavel Begunkov <asml.silence@gmail.com>]

The next propagation bits are done similarly as it was before, but
- nxt stealing is now at top-level, but not hidden in handlers
- ensure there is no with REQ_F_DONT_STEAL_NEXT

v2:
- fix race cond in io_put_req_submission()
- don't REQ_F_DONT_STEAL_NEXT for sync poll_add

v3: [patch 3/3] only
- drop DONT_STEAL approach, and just check for refcount==1

Pavel Begunkov (3):
  io_uring: make submission ref putting consistent
  io_uring: remove @nxt from handlers
  io_uring: get next work with submission ref drop
