The stability-fix-approved label exists to denote that a PR increases stability in a repository that would otherwise have changes locked down; allowing the PR to merge.
Application of this label is restricted to openshift-team-leads and openshift-staff-engineers.
When it is determined by the architects that a team's repo(s) should be locked down from additional changes due to ongoing regressions, the label must be added to the respective tide merge queries.
This is a simple, manual process that involves creating a PR in openshift/release. This example shows how to require the label on all branches of the openshift/cluster-api repo.
Once the PR is merged, no changes will be able to be merged in the respective repo(s) without the stability-fix-approved label present.
openshift-team-leads and openshift-staff-engineers
can add the stability-fix-approved label to any PR by simply commenting /label stability-fix-approved on the PR. At that point, that PR will no longer be blocked and will follow the standard review and merge process.
