[PATCH 0/4] clean up deferred tw wakeups

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

While reviewing io_req_local_work_add() I haven't found any real problems,
but there are defintely rought edges. Remove one extra smp_mb__after_atomic(),
add comments about how the synchronisation works, and improve mixing lazy with
non-lazy work items.

Pavel Begunkov (4):
  io_uring: adjust defer tw counting
  io_uring: clean up local tw add-wait sync
  io_uring: clean *local_work_add var naming
  io_uring: combine cq_wait_nr checks
