Actually, if you guys would design something a littler newer than circa 1973 for your buffer cache design, things would be easier. The buffer cache acts this way becuase it is based on a PRIMITIVE design that's not far off from the textbook description found in "UNIX: a practical implementation." Novell was doing mirroring and distributed mirroring since about 1984. We are just trying to get linux closer to the 1990's.
