[GIT PULL] io_uring fixes for 5.18-rc3

[Jens Axboe]

Hi Linus,

- Ensure we check and -EINVAL any use of reserved or struct padding.
  Although we generally always do that, it's missed in two spots for
  resource updates, one for the ring fd registration from this merge
  window, and one for the extended arg. Make sure we have all of them
  handled. (Dylan)

- A few fixes for the deferred file assignment (me, Pavel)

- Add a feature flag for the deferred file assignment so apps can tell
  we handle it correctly (me)

- Fix a small perf regression with the current file position fix in this
  merge window (me)

Please pull!
