"Age" is hugely misleading, I think everybody agrees, but we are still in a stable series, and a global name change would just make it harder to apply patches.
There are very few places where "age" comes in. Not my call, but I doubt we're so frozen as to have to stick with that name.
That said, I think BSD uses "weight". It's not a lot better, but at least you know that the more heaviliy weighted page is one with the higher weight value, whereas we have "age up" meaning "make younger" :-/ And how can age go up and down anyway? I'd prefer to talk about ->temperature, more in line with what we see in the literature. But then, it's so easy to talk about "aging", what would it be with ->temperature: Heating? Cooling? Stirring? ;-)
That's much _much_ better: I'd go for "warmth" myself, warm_page_up() and cool_page_down(). I particularly like the ambiguity, that a warmer page may be a more recently used page or a more frequently used page.
