Subject: [PATCH v5 14/14] software node: remove separate handling of references
Date: Fri, 11 Oct 2019 16:07:21 -0700	[thread overview]
Message-ID: <20191011230721.206646-15-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20191011230721.206646-1-dmitry.torokhov@gmail.com>

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