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!
