From 37a09f07459753e7c98d4e21f1c61e8756923f81 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 30 Nov 2010 12:42:34 -0500 Subject: [PATCH] NFS: Fix a readdirplus bug When comparing filehandles in the helper nfs_same_file(), we should not be using 'strncmp()': filehandles are not null terminated strings. Instead, we should just use the existing helper nfs_compare_fh().
