I never stated that the cache would (or should!) hold the whole kernel. It will, obviously, hold some data and user code. But it's a time-tested rule of thumb that, to a first approximation, your cache should equal the size of the kernel. (In the case of UNIX, the kernel should be trimmed to include only the devices that are actually present).home | help
