Jens Axboe ac90f249e1 io_uring: expose single mmap capability ... After commit 75b28affdd we can get by with just a single mmap to map both the sq and cq ring. However, userspace doesn't know that. Add a features variable to io_uring_params, and notify userspace that the kernel has this ability. This can then be used in liburing (or in applications directly) to avoid the second mmap.
