Subject: [PATCH 30/59] NET: Remove netfilter scaffolding for lsm_export
Date: Tue,  9 Apr 2019 14:39:17 -0700	[thread overview]
Message-ID: <20190409213946.1667-31-casey@schaufler-ca.com> (raw)
In-Reply-To: <20190409213946.1667-1-casey@schaufler-ca.com>

Remove scaffolding functions from the netfilter code.
Replace with direct access to lsm_export fields so as
to be explicit about how the secmarks are being
handled.
