Subject: [PATCH v3 08/15] NFSD: Clean up nfsd_dispatch() variables
Date: Thu, 01 Oct 2020 18:59:28 -0400 [thread overview]
Message-ID: <160159316832.79253.9696512483283981117.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <160159301676.79253.16488984581431975601.stgit@klimt.1015granger.net>
For consistency and code legibility, use a similar organization of
variables as svc_generic_dispatch().
