io_uring is fundamentally under-designed and will never work correctly. It cannot be incrementally reformed.

You'll need to say a little more than that to be taken seriously. Are you just against all things new, or is there something in the core API that is a bad idea? Surely you're not against the idea of ringbuffers in general, or saying "new thing bad, grug like old thing"?

Pretty much everything high performance is ringbuffers these days, e.g. NVMe. What makes io_uring the one thing that cannot be done?

Care to elaborate?
