Well, it is not a big win if that is what you meant. Those two fields are only being used when dealing with deferred pages, which only happens at boot time. If later on, free_area_init_node gets called from memhotplug code, we will also set the fields, although they will not be used. Is this a problem? No, but I think it is more clear from the code if we see when this is called. So I would say it was only for code consistency. If you think this this is not worth, I am ok with dropping it.
