From c3ba13298709f46e72b22d087d0aa02bd012e4b0 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 30 Oct 2017 08:13:14 -0700 Subject: cgroup: mark @cgrp __maybe_unused in cpu_stat_show() The local variable @cgrp isn't used if !CONFIG_CGROUP_SCHED. Mark the variable with __maybe_unused to avoid a compile warning.
