In 4.16.7 it is the dst_release in:

static inline void ip_rt_put(struct rtable *rt)
{
        /* dst_release() accepts a NULL parameter.
         * We rely on dst being first structure in struct rtable
         */
        BUILD_BUG_ON(offsetof(struct rtable, dst) != 0);
--->    dst_release(&rt->dst);
}
