Hi @jseseCCS. Thanks for your PR.

I'm waiting for a openshift 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.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

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.

to merge reviewer:

This PR replaces #105976.

While reviewing my open PRs, I realized these 4.21 changes hadn't been merged and the previous PR had significantly diverged from the base branch. I'm making it right by opening this fresh PR to ensure 4.21 stays accurate.

@jseseCCS You need to follow the steps to join the openshift org, so you don't keep running into this. I'll send you the link to the source page with instructions over slack.
