From db3a3bcf08d5c79290b369d70cc0b80c369d8ad9 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 20 Jun 2012 15:50:14 -0400 Subject: [PATCH] NFSv2/v3: Remove incorrect dprintks from the readdir reply code The actual size of the directory is unknown to the client, so it is always requesting the maximum number it can handle. If the server is replying with fewer entries than was requested, then that will usually reflect the fact that we've hit the end of the directory. Flagging it as an error is therefore incorrect.
