Message-ID: <420496F7.9080900@csua.berkeley.edu> (raw)

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.
