related issue: #1274

If the all object of a specific GVK supports DisableDeepCopy option, the risk is too great. it may be a better way to specify DisableDeepCopy option every time list function is called

example code

out := corev1.PodList{}
cache.List(context.Background(), &out, client.UnsafeDisableDeepCopy)

Hi @qiankunli. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

/ok-to-test

// disableDeepCopy indicates not to deep copy objects during list objects.
// Be very careful with this, when enabled you must DeepCopy any object before mutating it,
// otherwise you will mutate the object in the cache.

Please add a test for this, maybe by checking that the pointer for the obj is the same as for the one in the cache
