List-Post: List-Help: List-Subscribe: , List-Archive: This patch appears to have the effect that non-existent files don't get cached. When I apply it to 2.6.10, a C preprocessor workload that involves opening lots of non-existent files slows down by an order of magnitude and I notice tens of thousands of NFS ACCESS calls per second according to nfsstat.
