I just half-throughly waded through the sysutils/fusefs-kmod sources, and
you're right; there's no mentioning of sizeof(struct vnode) in all of the
preprocessed sources (at least none that I could find, directly or
indirectly). So, if struct vnode only grows and none of the original fields
are moved due to padding issues (or gcc reordering fields because of
padding), the old kernel module should work unchanged.
To finish: sorry for the noise, and sorry for the panic I might've provoked.
