I was looking at this group:
static inline int page_xchg_last_nid(struct page *page, int nid) static inline int page_last_nid(struct page *page) static inline void reset_page_last_nid(struct page *page)
IMO the best naming for these would be page_nid_xchg_last(), page_nid_last() and page_nid_reset_last().

But those schemes make no sense.
I don't see any benefit in being consistent with existing inconsistency. It's better to use good naming for new things and to fix up the old things where practical.
