| |
2.6.33-longterm review patch. If anyone has any objections, please let us know.
------------------
From: Dave Jones <davej@redhat.com>
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).
