That is, we will only trust a positive name cache entry for a specified amount of time before falling back to a LOOKUP RPC, even if the ctime for the file handle matches the cached copy in the name cache entry. The timeout is configured via a new 'nametimeo' mount option and defaults to 60 seconds. It may be set to zero to disable positive name caching entirely. END
