[GIT PULL] io_uring updates for 5.8-rc1

[GIT PULL] io_uring updates for 5.8-rc1

[Jens Axboe]

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!

I'm not sure why pr-tracker-bot didn't like your io_uring pull request.

It replied to your two other pull requests, but not to this one. I'm
not seeing any hugely fundamental differences between this and the two
others..

Pretty sure that happened last time too, but I don't know why. For
the incremental ones after the merge window, it seemed to work fine...
