[PATCH 5.14 053/334] sched/numa: Fix is_core_idle()
From: Greg Kroah-Hartman
Date: Mon Sep 13 2021 - 10:26:17 EST
From: Mika Penttilä <mika.penttila@xxxxxxxxx>
[ Upstream commit 1c6829cfd3d5124b125e6df41158665aea413b35 ]
Use the loop variable instead of the function argument to test the
other SMT siblings for idle.
Fixes: ff7db0bf24db ("sched/numa: Prefer using an idle CPU as a migration target instead of comparing tasks")
