Consolidate them in include/linux/string_helpers.h. Quite a few users of open coded yesno() could later be converted to the new function: $ git grep '?\s*"yes"\s*' | wc -l 286 $ git grep '?\s*"no"\s*' | wc -l 20 The inlined function should keep the const strings local to each compilation unit, the same way it's now, thus not changing the current behavior.
