Pull io_uring epoll update from Jens Axboe:
 "As discussed a few months ago, this pull request gets rid of allowing
  nested epoll notification contexts via io_uring.

  Nested contexts have been a source of issues on the epoll side, and
  there should not be a need to support them from io_uring. The epoll
  io_uring side exists mainly to facilitate a gradual migration from a
  notification based epoll setup to an io_uring ditto"
