struct page field arrangement

A change early last year reordered struct page so that ptl overlaps not only private, but also mapping. Since spinlock_t can be much larger, I'm wondering whether there's a reason to not also overlay the space index and lru take - are these used for anything on page table pages? Thanks, Jan - To u
