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!
