Quite a few other functions are declared in a header, but I don't see
any existing callers in tree. I wonder if the maintainer could
consider cleaning these up so that we don't retain them in binaries
without dead code elimination enabled, or if there's a need to keep
this code in line with an external upstream codebase?
