One of the points of this implementation is that it be able to preserve memory contents when there is no pressure. If those contents happen to contain a THP/KSM page, and there's no pressure, it seems like the right thing to do is to leave that memory in place. It might be a fair thing to do this in order to keep the implementation more sane at the moment. But, we should make sure there's some good text on that in the changelog. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
