Description of problem:
cpuset changes after kubelet service restarts.
Version-Release number of selected component (if applicable):
4.12.27
How reproducible:
100% in customer's cluster but 0% in my test lab
Steps to Reproduce:
1. Confirm cpu_manager_state before restarting kubelet service
# cat /var/lib/kubelet/cpu_manager_state |jq .
{
"policyName": "static",
"defaultCpuSet": "0-2,18,20-24,29-42,55,58,60-64,69-79",
"entries": {
"203009c3-760c-40d5-8a0d-39d28ec69bd7": {

},

"cnt7": "3-6,43-46"
}
},

}
2. Enable -v=4 in kubelet and restart the kubelet service
# cat /etc/systemd/system/kubelet.service.d/20-logging.conf
[Service]
Environment="KUBELET_LOG_LEVEL=4"
# sudo systemctl daemon-reload
# systemctl restart kubelet
# cat /var/lib/kubelet/cpu_manager_state
3. Check cpu_manager_state after kubelet restarts
$ cat /var/lib/kubelet/cpu_manager_state |jq .
{
"policyName": "static",
"defaultCpuSet": "0-2,19-22,27-42,56,59-62,67-79",
"entries": {
