2 years ago I suggested max_zone_idx.
Not insisting, but perhaps max_zoneidx would simply be shorter than
highest_zoneidx, while saying the same thing?
Also I wonder if we still need the accessor ac_classzone_idx() (before rename),
or just replace it with ac->highest_zoneidx (or whatever the final name is)
instead of renaming it?
Thanks!
