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 from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
