Nice optimization! I suppose that it is remnant from very early version of memory hotplug. Probably after a few patch series iterations hotplug_pages and balloon_hotplug lost their meaning and I did not catch it. Additionally, as I can see there is not any consumer for total_pages here. So, I think that we can go further and remove this obfuscated code at all.
