Mike Smith 98f8aa275b As described by the submitter: 
I did some tcpdumping the other day and noticed that GETATTR calls
  were frequently followed by an ACCESS call to the same file. The
  attached patch changes nfs_getattr to fill the access cache as a side
  effect. This is accomplished by calling ACCESS rather than
  GETATTR. This implies a modest overhead of 4 bytes in the request and
  8 bytes in the response compared to doing a vanilla GETATTR.
...
  [The patch comprises two parts] The first
  is the "real" patch, the second counts misses and hits rather than
  fills and hits. The difference is subtle but important because both
  nfs_getattr and nfs_access now fill the cache. It also changes the
  default value of nfsaccess_cache_timeout to better match the attribute
  cache. IMHO, file timestamps change much more frequently than
  protection bits.
