how can we use epoll_ctl to manage perfbuffer

like that

epoll1 = epoll::Epoll::new(epoll::EpollCreateFlags::empty()).unwrap();

perf = PerfBufferBuilder::new(map)
            .sample_cb(handle_event)
            .lost_cb(handle_lost)
            .build()?
            .into();

epoll1.add(perf.epoll_fd(), epoll::EpollEvent::new(epoll::EpollFlags::EPOLLIN, perf as *const _ as u64))

let mut events = [epoll::EpollEvent::empty()];
let event_count = epoll1.wait(&mut events, PollTimeout::from(u16::try_from(1000).unwrap()))
                    .unwrap();
for event in events.iter().take(event_count) {
                    let perf_ptr = event.data() as *mut PerfBuffer;
                    let _ = unsafe { (*perf_ptr).consume() 
};
}

but it can doesn't work
