If these things are built-in, can you verify you're saving bytes
with size before and after the patch?

I wonder if having something like DECLARE_SYSCTL_PATH_ONE() would make
this nicer on the eyes, and also useful for the other changes you
are making. Do you have many other single path entries you are changing
later?
