as I've said earlier. There are many code paths which are quite confusing and they expect sub-section granularity while they in fact won't work with sub memblock granularity. This is a larger project I am afraid and it would be great if you are willing to try to consolidate that code. I have that on my todo list but there are more pressing things to address first for me now. -- Michal Hocko SUSE Labs
