And yes, that patch already got merged. However, the patch to *allow* Kprobes with DEBUG_RODATA is not, and will not be. It's not a regression, and quite frankly, I don't think I would even want that patch. Kprobes fundamntally disagrees with DEBUG_RODATA, there's no point in "working around it". Better just admit it.
