Hi Linus,
Just a few odd fixes that should make it into -rc4:
- Fix a regression this merge window where cloning of registered buffers
didn't take into account the dummy_ubuf.
- Fix a race with reading how many SQRING entries are available, causing
userspace to need to loop around io_uring_sqring_wait() rather than
being able to rely on SQEs being available when it returned.
- Ensure that the SQPOLL thread is TASK_RUNNING before running task_work
off the cancelation exit path.
Please pull!
