From e37736777254ce1abc85493a5cacbefe5983b896 Mon Sep 17 00:00:00 2001 From: "Tu, Xiaobing" Date: Tue, 23 Oct 2012 01:03:00 +0200 Subject: Fix memory leak in cpufreq stats. When system enters sleep, non-boot CPUs will be disabled. Cpufreq stats sysfs is created when the CPU is up, but it is not freed when the CPU is going down. This will cause memory leak.
