Generally I'd say that it makes sense. Anything that wants to
access the method in question would either have to play with
set_fs() or open-code it; neither is good.
It makes sense to localize calls of a method when we have pretty
much mandatory framing for it (security_... stuff).
So the only question is whether it makes sense for anything other
than syscall itself to access the method in question. AFAICS,
the answer's yes...
