From: Guopeng Zhang <[email protected]>
check_isolcpus() clears ISOLCPUS before rebuilding it from sched domain
data. Comparing that empty value with
/sys/devices/system/cpu/isolated makes the test fail whenever
isolcpus=domain is present.
The cpuset.cpus.isolated check above and the sched domain check below
already validate their respective interfaces. Remove the comparison and
the unused HKICPUS read.
Fixes: 6df415aa46ec ("cgroup/cpuset: Defer housekeeping_update() calls from CPU
hotplug to workqueue")
