I can get this out pretty quickly, hopefully sometime next week. I had a long talk with Dan about this topic previously, and I'm not sure how we get more dynamic than this to be honest. nr_possible_nodes is *definitely* expected to be immutable after __init all over the kernel, it's used to allocate a memory. Surface area is very large here. ~Gregory
