3.2.53-rc1 review patch. If anyone has any objections, please let me know.

From: Bernd Schubert <bernd.schubert@itwm.fraunhofer.de>
commit 6a8a13e03861c0ab83ab07d573ca793cff0e5d00 upstream.
Those flags are supposed to be set by NFS readdir() to tell ext3/ext4 to 32bit (NFSv2) or 64bit hash values (offsets) in seekdir().
