balloon seems to only use

Can we directly use for_each_populated_zone(zone) here?

This appears to be covered by for_each_migratetype_order(order, mt) below.

yes, my example couldn't because I was still assuming per-node API

yes but
#define for_each_migratetype_order(order, type) \
for (order = 0; order < MAX_ORDER; order++) \
for (type = 0; type < MIGRATE_TYPES; type++)
so you would have to skip orders < min_order
