That's all the numa goop which Martin Hicks added. It's all disabled if z->reclaim_pages is zero (it is). However we could be testing that flag a bit earlier, I think.
And yeah, some de-spaghettification would be nice. Certainly before adding more logic.
Martin, should we take out the early zone reclaim logic? It's all unreachable at present anyway.
