Log:
  Make external NFS clients know when files have their attributes changed and
  avoid cache the file's state indefinitely. The va_filerev is what is sent
  to the client as the "change" attribute, the client is periodically fetching
  the attributes and without this option the attribute remains as some garbage
  value.
