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

Some improvements after killing refcounting, and other cleanups.

With 2/2 with will be only tracking reqs with
file->f_op == &io_uring_fops, which is nice.

Pavel Begunkov (5):
  io_uring: optimise iowq refcounting
  io_uring: don't inflight-track linked timeouts
  io_uring: optimise initial ltimeout refcounting
  io_uring: kill not necessary resubmit switch
  io_uring: deduplicate cancellation code
