Ok. Then largely we are in agreement. To implement that the rule is simple. If it isn't CTL_UNNUMBERED and the number is in Linus's tree, it is our responsibility to never change the meaning of that number. If a new sysctl entry is introduced it should be CTL_UNNUMBERED until it reaches Linus's tree to avoid conflicts. There is simply no point in having any kind of support for numbers whose meanings can change. Which is why I removed the few cases of binary number duplication I found.
