From 3a123bbbb10d54dbdde6ccbbd519c74c91ba2f52 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Wed, 24 May 2017 10:59:56 +0530 Subject: [PATCH] sched/fair: Drop always true parameter of update_cfs_rq_load_avg() update_freq is always true and there is no need to pass it to update_cfs_rq_load_avg(). Remove it.
