From 1a0ba9ae485c5fd17d0bff2f14d9dd75b8985593 Mon Sep 17 00:00:00 2001 From: Amnon Aaronsohn Date: Mon, 9 Apr 2007 22:05:26 -0700 Subject: [PATCH] NFS: statfs error-handling fix The nfs statfs function returns a success code on error, and fills the output buffer with invalid values. The attached patch makes it return a correct error code instead.
