When multiple epics are referenced in the PR body, each commit of the PR should reference the epic(s) that commit is part of and all epics listed in the commit messages should be listed in the PR body. These unexpected cases were found:
Error: These commits should have an epic or issue ref but don't: [https://github.com/cockroachdb/cockroach/commit/c21c3b4196b706a191041435970e2f04cc98e45f https://github.com/cockroachdb/cockroach/commit/9d612e44db11c7ae8ff31174f25fc2b96d43983f https://github.com/cockroachdb/cockroach/commit/2e2edb83eef41316b91eb4ec9620c3b9e6ce91c7 https://github.com/cockroachdb/cockroach/commit/43591ce2c7ba61d7f0d895257101d3f40b187646 https://github.com/cockroachdb/cockroach/commit/5d2c38239804a52ccac714bbfea9cd02c3602b7c https://github.com/cockroachdb/cockroach/commit/e5759cc73bb6b86d376b5b7d1c3c261f08633eea https://github.com/cockroachdb/cockroach/commit/f570e321941dd10946f6c52125db0d4d1498d671 https://github.com/cockroachdb/cockroach/commit/9cbd1da10549f364b30ffd68401c226f8d66c9ae]

Recommended reference placement:

If the PR relates to only one issue or Jira epic:

• Put the issue or Jira epic reference either in the PR description or in each relevant commit.
• If the reference is in the PR description, put Epic: None in each commit that doesn't relate to the epic. This is particularly important if the commit contains a release note.
  If the PR relates to multiple issues or Jira epics:
• Put the issue or Jira epic reference in each relevant commit.
• If a single commit relates to multiple Jira epics, put all relevant issue or Jira epic references in that commit.
• If all commits relate to all the Jira epics, put the issue or Jira epic references in the PR description or in all of the commit messages.
• Put Epic: None in each commit that doesn't relate to any issue or epic.
  If the PR relates to no issues and no Jira epics:
• Preferably, put Epic: None in the PR description or in each commit containing a release note.
