From 10d2c46f9408d404bffef89d5052953a3b1d9288 Mon Sep 17 00:00:00 2001 From: Nick Wilson Date: Thu, 22 Sep 2005 21:44:28 -0700 Subject: [PATCH] [PATCH] NFS: fix client oops when debugging is on nfs_readpage_release() causes an oops while accessing a file with NFS debugging turned on (echo 32767 > /proc/sys/sunrpc/nfs_debug) and a kernel built with CONFIG_DEBUG_SLAB. This patch moves the debugging statement above nfs_release_request() to avoid accessing freed memory.
