I think Andrea and David feel pretty strongly that we should remove the bitmap, unless we have some data to support keeping it. I don't feel as strongly about it, but I think their critique of it is pretty valid. I think the consensus is that the bitmap needs to go. The only real question IMNHO is whether we should do a power-of-2 or a length. But, if we have 12 bits, then the argument for doing length is pretty strong. We don't need anywhere near 12 bits if doing power-of-2. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
