The code is clear that it implements the "Adaptive Replacement Cache",
which is an algorithm proposed by IBM; the code probably references some
IBM papers on the topic -- and if not, discussions of ARC on -hackers
certainly do. I don't see how there could be any reasonable grounds for
arguing that, prior to this thread, we just "came up with something
really, really similar".
