In-Reply-To: <20110616000258.GA14529@kroah.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org 2.6.39-stable review patch. If anyone has any objections, please let us know. ------------------ From: Dave Jones commit 13f067537f34456443f61c950cd6dc37d1d5f3ee upstream. cpufreq_stats leaves behind its sysfs entries, which causes a panic when something stumbled across them. (Discovered by unloading cpufreq_stats while powertop was loaded).
