Epoll (efd1) has installed a\n\u003e callback wakeup entry on that queue, and the wake_up() performed by the\n\u003e \"dfd\" net code will end up in ep_poll_callback(). At this point epoll\n\u003e (efd1) notices that it may have some event ready, so it needs to wake up\n\u003e the waiters on its poll wait list (efd2). So it calls ep_poll_safewake()\n\u003e that ends up in another wake_up(), after having checked about the\n\u003e recursion constraints.
