   Title:   Adding an Uncacheable Directory-Entry Metadata Attribute to NFSv4.2

Abstract:

   Network File System version 4.2 (NFSv4.2) clients may cache the file
   attributes returned by READDIR alongside each directory entry.  This
   caching is inherently best-effort: those attributes belong to the
   underlying files and change when the files are written, which the
   directory's change attribute does not track.  In some deployments the
   rate of file writes by other clients makes such caching produce
   incorrect size and timestamp values often enough to be a deployment
   problem.  This document introduces an uncacheable dirent metadata
   attribute for NFSv4.2 that allows a server to identify a directory
   for which an honoring client is required to retrieve directory-entry
   metadata from the server on each READDIR rather than serving the
   response from a local cache.
