Hi! This is neat and quite cool - but one thing that keeps nagging me is what how much overhead does this cut from the existing setup when you use virtio (with guests obviously)? That is from a high level view the beaty of io_uring being passed in the guest is you don't have the virtio ring -> io_uring processing, right? Thanks!
