I suppose you are doing data copy in -poll instead of -read to
Hey, Rusty,
For virtualization, we've developed virtio_ring for efficient communication.
This would also work well for userspace-kernel communication, particularly
for things like the tun device. By using the same ABI, we can join guests
to the host kernel trivially.
I'm *sure* you meant to
