It seems that you’ve referenced an “undefined Pull Request” for the Thanos project, but there is no specific information provided. To create a summary, I would need details such as the title of the Pull Request, its purpose, the files affected, key changes made, and any relevant discussions or comments from the reviewers.

If you can provide me with more details about the Pull Request, such as its description, goals, and any important code changes, I would be happy to help you create a summary tailored for an advanced developer.
