Oh, yes, it is as simple as:
void
g_renew_provider(struct g_provider *pp)
{

	g_topology_assert();
	G_VALID_PROVIDER(pp);
	KASSERT(!(pp->geom->flags & G_GEOM_WITHER),
	    ("renew provider on WITHERing geom(%s) (class %s)",
	    pp->geom->name, pp->geom->class->name));
	g_post_event(g_new_provider_event, pp, M_WAITOK, pp, NULL);
}

I actually borrowed it from a patch of yours :-)
