Memory usage for The default mininum slab alignment in UP is 8 bytes which means you can use 3 bits. And as far as I can see only the lower two bits are used. You still have one bit leftover. (current upstream that is did not check if you modified it). -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
