For all the comments about ioctl and APIs...

There isn't a lot of options when it comes to the basic interface to an API. You have functions and their arguments. They can be strongly typed like most random syscalls or generic like ioctl or some microkernels. io_uring's API is not so nice in the sense it is very generic on the surface and typing is handled in the data structure rather than signature so it needs wrapping for any language level typing support. And that that point, besides some internal details, what separates ioctl from io_uring? Could I not send similar data to ioctl and have it act similarly? At the end of the day it is just a way to shuffle data to and from the kernel. How the kernel acts on that is what matters.
