Hi @stpabhi. Thanks for your PR.

I'm waiting for a kubeflow 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.

Thanks for the fix.

@stpabhi Can you update the PR description to explain what the problem is and how this fixes it?

@jlewi both this and #2154 should be merged since they are correctly returning the children created by a controller during sync (every 20sec). Profiles/Permission controllers also need something similar.

Thanks @kkasravi I reviewed #2154
