From 9783be2c0e90bbaceec3c471c4fb017bff7293ba Mon Sep 17 00:00:00 2001 From: Joel Fernandes Date: Fri, 15 Dec 2017 07:39:43 -0800 Subject: [PATCH] sched/fair: Correct obsolete comment about cpufreq_update_util() Since the remote cpufreq callback work, the cpufreq_update_util() call can happen from remote CPUs. The comment about local CPUs is thus obsolete. Update it accordingly.
