Subject: [PATCH v3 13/13] software node: remove separate handling of references
Date: Mon,  9 Sep 2019 01:15:57 -0700	[thread overview]
Message-ID: <20190909081557.93766-14-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20190909081557.93766-1-dmitry.torokhov@gmail.com>

Now that all users of references have moved to reference properties,
we can remove separate handling of references.
