From 4267c9561d9c3bb2abf45abed9c75a1c892d7d15 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 13 Feb 2008 14:55:17 -0500 Subject: [PATCH] NFS: Allow text-based mounts via compat_sys_mount The compat_sys_mount() system call throws EINVAL for text-based NFSv4 mounts. The text-based mount interface assumes that any mount option blob that doesn't set the version field to "1" is a C string (ie not a legacy mount request). The compat_sys_mount() call treats blobs that don't set the version field to "1" as an error. We just relax the check in compat_sys_mount() a bit to allow C strings to be passed down to the NFSv4 client.
