| From | Andi Kleen <> | Subject | [PATCH] [54/99] CPUFREQ: Remove cpufreq_stats sysfs entries on module unload. | Date | Wed, 27 Jul 2011 14:48:53 -0700 (PDT) |
| |
2.6.35-longterm review patch. If anyone has any objections, please let me 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).
