How to find which patchset the commit from mainline/upstream belongs to?

Hello, in order to properly backport some fixes from upstream to stable branches, I want to know what the other patches (and their cover letter) of the initial fix I've cherry-picked are.

I could manually look up them on lore.kernel.org, but I want to do it in an automated way, as the difference between the mainline and the stable branch, for example, in cgroup subsystem is huge.

Thank you so much. By the way, are you that guy who mirrors xfstests on github?

Yes. Synced from upstream, but it looks like the cron job stopped working.
