Hi Linus,

A relatively quiet round, mostly just fixes and code improvements. In
particular:

- Make statx just use the generic statx handler, instead of open coding
  it. We don't need that anymore, as we always call it async safe
  (Bijan)

- Enable closing of the ring itself. Also fixes O_PATH closure (me)

- Properly name completion members (me)

- Batch reap of dead file registrations (me)

- Allow IORING_OP_POLL with double waitqueues (me)

- Add tee(2) support (Pavel)

- Remove double off read (Pavel)

- Fix overflow cancellations (Pavel)

- Improve CQ timeouts (Pavel)

- Async defer drain fixes (Pavel)

- Add support for enabling/disabling notifications on a registered
  eventfd (Stefano)

- Remove dead state parameter (Xiaoguang)

- Disable SQPOLL submit on dying ctx (Xiaoguang)

- Various code cleanups

Please pull!
