Hi, I'm trying to implement SQPOLL in netty at the moment, basically the fd are registered by io_uring_register(2), which returns 0, but the write event seems to fail with bad file descriptor error(-9) when SQPOLL flag is enabled small example to reproduce it: https://gist.github.com/1Jo1/171790d549134b5b81ee51b23fb15cd0 what exactly am I doing wrong here? :) --- Josef
