My point is that having to ensure that each arch zeroes out this structure is difficult/costly/unreliable/fragile. It would be better if we can reliably clear it at some well-known place in core MM. That might mean that the memory gets cleared twice on some architectures, but I doubt if that matters - it's a once-off thing. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
