Always a good idea to name things. However, "exclusive" is
not that clear to me. Given that the argument is supposed
to indicate whether we map a single or a compound page,
maybe the names in the enum could just be SINGLE and COMPOUND?
Naming the enum should make it clear enough what it does:
enum rmap_page {
SINGLE = 0,
COMPOUND
}

Would it make sense to use the name in the argument to that function,
too?
I often find it a lot easier to see what things do if they use symbolic
names, rather than by trying to remember what each boolean argument to
a function does.
