Description Artyom 2021-05-13 10:27:16 UTC

Description of problem:
Our recent change to introduce support for workload managements, also introduced a new log message under the CPU manager reconcile loop that floods the kubelet log once the CPU manager enabled.

Version-Release number of selected component (if applicable):
master

How reproducible:
Always

Steps to Reproduce:
1. Configure CPU manager with the static policy
2. Check the kubelet log
3.

Actual results:

Expected results:
No flood, probably we should reduce the verbosity or remove the message at all.
