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.
