Feel free to ignore my comment, seems good otherwise.
src/hotspot/share/runtime/registerMap.hpp line 75:
> 73: enum class UpdateMap { skip, yes };
> 74: enum class ProcessFrames { skip, yes };
> 75: enum class WalkContinuation { skip, yes };
Instead of `yes` I would recommend using like `include` (or `add') as `yes`
seems relatively unspecific compared to `skip`.
