If it is a commit that has landed already, I think it would be nice to mention the commit in the usual "commit + 12 character SHA1" format. If it is a change in a series that has not landed yet, it would be nice if you could provide a link to the series, e.g. after the commit log (after the "---"). Kind regards, Niklas
