Subject: [PATCH v4 14/14] software node: remove separate handling of references
Date: Tue, 10 Sep 2019 22:12:31 -0700 [thread overview]
Message-ID: <20190911051231.148032-15-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20190911051231.148032-1-dmitry.torokhov@gmail.com>
Now that all users of references have moved to reference properties,
we can remove separate handling of references.
