Subject: [PATCH v1 21/23] SUNRPC: Make AUTH_SYS and AUTH_NULL set au_verfsize
Date: Mon, 11 Feb 2019 11:25:31 -0500
Message-ID: <20190211162531.2817.34469.stgit@manet.1015granger.net> (raw)
In-Reply-To: <20190211161920.2817.20881.stgit@manet.1015granger.net>

au_verfsize will be needed for a non-flavor-specific computation
in a subsequent patch.
