+        The upstream process for stable tree updates is quite similar
+        in scope to the Ubuntu SRU process, e.g., each patch has to
+        demonstrably fix a bug, and each patch is vetted by upstream
+        by originating either directly from a mainline/stable Linux tree or
+        a minimally backported form of that patch. The v4.4.9 upstream stable
+        patch set is now available. It should be included in the Ubuntu
+        kernel as well.
