Hi Linus,

Here are the io_uring updates for 5.10. This pull request contains:

- Add blkcg accounting for io-wq offload (Dennis)

- A use-after-free fix for io-wq (Hillf)

- Cancelation fixes and improvements

- Use proper files_struct references for offload

- Cleanup of io_uring_get_socket() since that can now go into our own
  header

- SQPOLL fixes and cleanups, and support for sharing the thread

- Improvement to how page accounting is done for registered buffers and
  huge pages, accounting the real pinned state

- Series cleaning up the xarray code (Willy)

- Various cleanups, refactoring, and improvements (Pavel)

- Use raw spinlock for io-wq (Sebastian)

- Add support for ring restrictions (Stefano)

Please pull!
