[PATCH 1/2] sched: Misc preps for cgroup unified hierarchy interface

From: Tejun Heo
Date: Mon Sep 25 2017 - 12:01:01 EST


Make the following changes in preparation for the cpu controller
interface implementation for cgroup2. This patch doesn't cause any
functional differences.

* s/cpu_stats_show()/cpu_cfs_stat_show()/

* s/cpu_files/cpu_legacy_files/

v2: Dropped cpuacct changes as it won't be used by cpu controller
interface anymore.
