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

  I always assumed it's the verb uring[1], but that might well be wrong. [1]: https://en.wiktionary.org/wiki/uring https://en.wiktionary.org/wiki/uring

  It’s a ring buffer. Not sure what the u is. Micro?

    userspace?

    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.

  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.

  Userspace ring buffers.
