+Borrowed commits
+================
+
+For work that started in other projects (e.g. the Linux kernel and
+Git), I've cherry-picked the relevant commits from the project
+repositories to preserve commit metadata.  For each of these commits,
+I've attached a note with the commit hash, original commit message,
+and original commit repository.  Fetch the `refs/notes/commits`
+reference from my public repository if you want these notes.
+
+If I altered the original patch by removing context, I've added my
+s-o-b.  Otherwise the original patch applied cleanly, and I left my
+s-o-b off.
