   Title:   Adding an Uncacheable Dirent Metadata Attribute to NFSv4.2
   Author:  Thomas Haynes
   Name:    draft-ietf-nfsv4-uncacheable-directories-11.txt
   Pages:   18

Abstract:

   Network File System version 4.2 (NFSv4.2) clients may cache the file
   attributes returned by READDIR alongside each directory entry.  Such
   a cache is not invalidated by the directory's change attribute, which
   reflects changes to the directory and its entries but not writes to
   the files those entries name, so it can become stale when another
   client changes one of those files.  In some deployments this produces
   incorrect size and timestamp values often enough to be a 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 goes to the server for each enumeration, and does not
   report an entry's attributes from a value it held before that
   READDIR.
