This patch greatly clarifies the code, making it more precise. I'm
always in favor for replacing fuzzy, english phrases in code with
terse, precise terms.

That was my favorite hunk of the patch. Now it's obvious the the two
lines are checking essentially the same thing. In fact, we can probably
drop the tiling check here. The miptree check should be sufficient (and
if it's not, that's a bug in my opinion).
