Don't bother about it. What you're trying to do gives you no tangible benefit if you did manage to do it.
Linux uses all memory not allocated by processes as disk buffer. Be glad about it. Of course, if one process suddenly allocates all memory (and more) your disk buffer size drops to zero. Nothing you can do to avoid this, it's actually smart to do it that way. If you absolutely have to keep some files in RAM for some reason, use a ram disk (why? didn't you say you had a fast disk?).
