I fully agree with you here. But we check for the genid just in
rt_init_metrics() which is invoked only on route cache entry
creation. There is no check when the metrics are accessed,
because the metrics on the inetpeer are valid on every access.

Every routing cache entry we will use after the flush will be
a newly created one!  All the old ones will be stop being used.

Yes, I know that. All inetpeer metrics are updated once with the
first new routing cache entry that binds that inetpeer to the route.
