I thought about this a bit, and maybe I missed your original point- today we are able to do all the needed cleanup for rds-tcp when we unload the module, even though network activity has not quiesced, and there is no reason we cannot use the same code for netns cleanup as well. I think this is what you were trying to ask, when you said "why do you need to know that loopback is down?" I'm sorry I missed that, I will re-examine the code and get back to you- it should be possible to just do one registration and cleanup rds-state and avoid the hack of registering twice (saw your most recent long mail- sorry- both v1 and v2 are hacks) I'm on the road at the moment, so I'll get back to you on this.
