Not sure this will help since no tool checks structure isn't
actually used even though it's in internal.
If you want to go overboard it's solvable of course, e.g.
something like this will work:
E.g. in virtio.h
#ifndef VIRTIO_PRIVATE
#define VIRTIO_PRIVATE(f) (VIRTIO_PIVATE_##f)
#endif
struct VirtioPrivate {
int VIRTIO_PRIVATE(bar);
};
and in virtio.c:
#define VIRTIO_PRIVATE(f) (f)
#include <virtio.h>
