+Subject: [PATCH] cmd/link: mark unexported methods for plugins
+
+When plugin is used, we already mark all exported methods
+reachable. However, when the plugin and the host program share
+a common package, an unexported method could also be reachable
+from both the plugin and the host via interfaces. We need to mark
+them as well.
+
+Fixes #51621.
