I'd rather not export something like this which pokes deep into
internals.  That being said I've been working on off on a
EXPORT_SYMBOL_FOR() that just exports a symbol to one specific module.
Hopefully I'll finish it for the next merge window, and with that
I'd feel much more comfortable with an export.
