* Removed unsafe double RLock in cpumanager ([#62464](https://github.com/kubernetes/kubernetes/pull/62464), [@choury](https://github.com/choury))

## Non-user-facing changes

- Passing an invalid policy name in the `--cpu-manager-policy` flag will now cause the kubelet to fail instead of simply ignoring the flag and running the `cpumanager`’s default policy instead. ([#80294](https://github.com/kubernetes/kubernetes/pull/80294), [@klueska](https://github.com/klueska))

            String s2 = opt2.getOpt() != null ? opt2.getOpt() : opt2.getLongOpt();
            return s1.compareToIgnoreCase(s2);
        }
    }

    private static class CLIManagerExtension extends CLIManager {
        public Collection<Option> getOptions() {
            List<Option> optList = new ArrayList<>(options.getOptions());
            optList.sort(new OptionComparator());
            return optList;
        }
    }

	// This is different from `internal.NewDefaultFieldManager` because:
	// 1. We don't want to create a `internal.FieldManager`
	// 2. We don't want to use the CapManager that is tested separately with
	// a smaller than the default cap.
