Sure

I also feel it may flow better by moving all changes related to  
'unreclaimable' such as owner field for VA, flags for types of owners,  
storing unreclaimables to LRU, etc. to later after all changes dealing  
with reclaimables are introduced. The unreclaimables are only of concern  
when OOM is involved so it'd be better to do them right before OOM.
