In-Reply-To: <20010621190103.A888@jmcmullan.resilience.com> <20010624140114.A10745@jmcmullan.resilience.com> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I read this thread as asking the question: If VM management is viewed as an optimization problem, then what exactly is the function that you are optimizing and what are the constraints? If you could express that well with a even a very loose model, then the code could be reviewed to see if it was really doing what was intended and assumptions could be tested. This seems like a reasonable request. Jason McMullan wrote: > On Sun, Jun 24, 2001 at 12:04:43PM -0300, Rik van Riel wrote: > > OK.
