> I really like the cleanups you’ve done in this area of the code base and this one is no exception. Looks good, just one question around the different G1ConcRefinement-flags (threshold and zones). Couldn’t we make these be number of cards and get rid of the buffers_to_cards conversion in g1ConcurrentRefine.cpp?

Those are product options; changing their semantics like that is not so easy.
