OT: What does io_uring stand for? I get the io part, but what is uring? Is that an abbreviation for something?

The interface uses ringbuffers for communication between the kernel and userspace. That's how I have always understood it at least, not sure if it's actually correct.

No, it is two ring buffers, with the kernel in between moving requests from one side to the other. My guess is that the name describes the shape.

I always assumed it's the verb uring[1], but that might well be wrong.
