Yes, setting base-commit is the right solution here -- it will tell you exactly where in the tree it belongs. In its absence, tools like b4 will also try to guess where the series might belong by comparing the file index information mentioned in the patches. It's a clever, but not exact process, because the patch may depend on changes in the files that aren't being modified. In general, having a base-commit: line in the cover letter or first patch is absolutely the right way to go. -K
