Hi, I found a bug submitting a server socket poll in io_uring. The file descriptor is not really closed when calling close(2), if I bind a new socket with the same address & port I'll get an "Already in use" error message example to reproduce it https://gist.github.com/1Jo1/3ace601884b86f7495fd5241190494dc tested on 5.9-rc2 --- Josef
