While we're on this topic, can someone explain to me what the special
CONFIG_NET_NS code in net/ipv4/route.c:rt_do_flush() is trying to

If the issue is that there is an implicit ordering of releasing of
'dst' entries that must be maintained, we really ought to formalize
it (f.e. with dependency pointers or something like that).
