Does anyone know of a tool for tracking patch backports accross multiple git branches? The commit ID changes when backport so you need to in most cases index off the patch subject (sometimes you can check for a 'backported' lien). Then often for that branch, I want to see which tags have the backport. Before I write something to do this, does something already exist? I want to do this generically for a bunch of different upstream projects, so not a project-specific solution.
