This is deferred to 3)\n\n2) The per destination limit is checked/updated.\n   This might add a new node in inetpeer tree.\n\n3) icmp_global_consume() consumes tokens if prior operations succeeded.\n\nThis means that host wide ratelimit is still effective\nin keeping inetpeer tree small even under DDOS.\n\nAs a bonus, I removed icmp_global.lock as the fast path\ncan use a lock-free operation."
