Eh, no? The linker does that across translation units anyway - moreover,
given that you make them static inlines, "yes" and "no" will still live
in .rodata.strX.Y in each individual TU that uses the yesno() helper.

The enableddisabled() is a mouthful, perhaps the helpers should have an
underscore between the choices

Pet peeve: Can we please stop using linux/kernel.h as a dumping ground
for every little utility/helper? That makes each and every translation
unit in the kernel slightly larger, hence slower to compile. Please make
a linux/string-choice.h and put them there.
