Looks good to me. But @jingxu97 suggested to have feature gate at https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/cm/container_manager_linux.go#L597, I don't have a strong opinion on where to feature gate though.

re #53684 (comment),
I thought about doing it there as well, but felt this was the best way to turn off this specific behavior. I also wanted as small of a cherrypick as possible.
