In the sysctl code there are a lot of duplicate constants used to validate the user input, which could be put in a shared place. Some of them are not even constant, fix this with the following patches. The first one declares the shared constants, the second one makes use of them for the kernel/ sysctls. If merged, I will send separate patches for the other susystems.
