eve.sys.linux.uring

Syscall wrappers and submission helpers for Linux io_uring.

This module builds on top of core.sys.linux.io_uring, which provides the structure definitions and constants from the kernel ABI. This module adds:

There is no compile-time version check. Call io_uring_setup and handle

ENOSYS to detect kernel support at runtime.
