> Hi all,
> can I have reviews for this change that improves the way G1 iterates over Howl-Full containers (i.e. "Full" cardsetptrs within a Howl cardset container)? Instead of calling the visitor method `do_card` to mark a single card for all cards in the range, just call the range-based visitor method `do_card_range`. This is also a little bit more efficient.
> This change is a requirement for [JDK-8275056](https://bugs.openjdk.java.net/browse/JDK-8275056).
> Testing: tier1-5
