Another thing that terribly confused me was this: in the vq struct you
have guest_notifier and host_notifier of type EventNotifier and in the
virtio binding structs you have guest_notifier and host_notifier which
are function callbacks.
Also, these vq->{guest_|host_}notifier assignments weren't easily found
using grep because they're assigned by assigning a pointer value and
initialising that pointer. Thanks to Juan for finding that for me :-)
