[GIT PULL] io_uring updates for 6.9-rc1

[GIT PULL] io_uring updates for 6.9-rc1

[Jens Axboe]

Hi Linus,

Here are the io_uring changes queued for the 6.9 kernel release. This
pull request contains:

- Make running of task_work internal loops more fair, and unify how the
  different methods deal with them (me)

- Support for per-ring NAPI. The two minor networking patches are in a
  shared branch with netdev. (Stefan)

- Add support for truncate (Tony)

- Export SQPOLL utilization stats (Xiaobing)

- Multishot fixes (Pavel)

- Fix for a race in manipulating the request flags via poll (Pavel)

- Cleanup the multishot checking by making it generic, moving it out of
  opcode handlers (Pavel)

- Various tweaks and cleanups (me, Kunwu, Alexander)

Please pull!
