[GIT PULL] io_uring updates for 6.11-rc1

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Sending this one early as I'm out on vacation.

Here are the io_uring updates queued up for the 6.11 merge window.
Nothing major this time around, various minor improvements and
cleanups/fixes. This pull request contains:

- Add bind/listen opcodes. Main motivation is to support direct
  descriptors, to avoid needing a regular fd just for doing these two
  operations (Gabriel)

- Probe fixes (Gabriel)

- Treat io-wq work flags as atomics. Not fixing a real issue, but may
  as well and it silences a KCSAN warning (me)

- Cleanup of rsrc __set_current_state() usage (me)

- Add 64-bit for {m,f}advise operations (me)

- Improve performance of data ring messages (me)

- Fix for ring message overflow posting (Pavel)

- Fix for freezer interaction with TWA_NOTIFY_SIGNAL. Not strictly an
  io_uring thing, but since TWA_NOTIFY_SIGNAL was originally added for
  faster task_work signaling for io_uring, bundling it with this pull.
  (Pavel)

- Add Pavel as a co-maintainer

- Various cleanups (me, Thorsten)

Please pull!
