This seems more interesting as demonstration of the amortized performance increase you'd expect from using io_uring, or as a tutorial for using it. I don't understand why I'd switch from using something like eza. If I'm listing 10,000 files the difference is between 40ms and 20ms. I absolutely would not notice that for a single invocation of the command.

Yeah, I wrote this as a fun little experiment to learn more io_uring usage. The practical savings of using this are tiny, maybe 5 seconds over your entire life. That wasn't the point haha

It's a very cool experiment. Just wanted to perhaps steer the conversation towards those things rather than whether or not this was a good ls replacement because like you say that feels like it was missing the point
