Looking through the series, it seems to mix bug fixes with new feature work. Would it make sense to split out the fixes so they can land independently, and keep the new features as a separate patchset? I'm currently rolling out crashdump CMA across the Meta fleet, so right now I care mostly about picking up isolated bug fixes. As it stands, it's difficult to tell which patches are fixes and which are features.
