[GIT PULL] Final io_uring updates for 6.14-rc1

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Followup pull request for io_uring for the 6.14 merge window. This pull
request contains:

- Series cleaning up the alloc cache changes from this merge window, and
  then another series on top making it better yet. This also solves an
  issue with KASAN_EXTRA_INFO, by making io_uring resilient to KASAN
  using parts of the freed struct for storage.

- Cleanups and simplications to buffer cloning and io resource node
  management.

- Fix an issue introduced in this merge window where READ/WRITE_ONCE was
  used on an atomic_t, which made some archs complain.

- Fix for an errant connect retry when the socket has been shut down.

- Fix for multishot and provided buffers.

Please pull!
