[GIT PULL] io_uring fixes for 6.15-rc6

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

A few io_uring fixes that should go into the 6.15 kernel release. This
pull request contains:

- Fix for linked timeouts arming and firing wrt prep and issue of the
  request being managed by the linked timeou.

- Fix for a CQE ordering issue between requests with multishot and using
  the same buffer group. This is a dumbed down version for this release
  and for stable, it'll get improved for 6.16.

- Tweak the SQPOLL submit batch size. A previous commit made SQPOLL
  manage its own task_work and chose a tiny batch size, bump it from 8
  to 32 to fix a performance regression due to that.

Please pull!
