关于UDP超时

从源码上看，应该是这一段代码。
它没有去把相关联的链路拆掉。
/*
* Unlink a destination from the given service
*/
static void __ip_vs_unlink_dest(struct ip_vs_service *svc,
struct ip_vs_dest *dest,
int svcupd)
{
dest->flags &= ~IP_VS_DEST_F_AVAILABLE;

/*
* Remove it from the d-linked destination list.
*/
list_del(&dest->n_list);
svc->num_dests--;
if (svcupd) {
/*
* Call the update_service function of its scheduler
*/
svc->scheduler->update_service(svc);
}
}
