From 8971a1016b9db4164c3c1b47ae1fde2818becf91 Mon Sep 17 00:00:00 2001 From: NeilBrown <neilb@suse.de> Date: Wed, 14 Feb 2007 00:33:11 -0800 Subject: [PATCH] knfsd: fix return value for writes to some files in 'nfsd' filesystem Most files in the 'nfsd' filesystem are transactional. When you write, a reply is generated that can be read back only on the same 'file'. If the reply has zero length, the 'write' will incorrectly return a value of '0' instead of the length that was written. This causes 'rpc.nfsd' to give an annoying warning. This patch fixes the test.
