[PATCH] Support for cached lookups via readdirplus [6/6]

From: Trond Myklebust (trond.myklebust@fys.uio.no)
Date: Sun Jul 28 2002 - 10:26:48 EST


Add support for the glibc 'd_type' field in cases where we have the
READDIRPLUS file attribute information available to us in
nfs_do_filldir().

Cheers,
  Trond
