Subject: [PATCH v3 23/26] NFS: rename nfs_fs_context pointer arg in a few functions
Date:   Wed, 11 Sep 2019 12:16:18 -0400
Message-Id: <20190911161621.19832-24-smayhew@redhat.com>
In-Reply-To: <20190911161621.19832-1-smayhew@redhat.com>
References: <20190911161621.19832-1-smayhew@redhat.com>
Sender: linux-nfs-owner@vger.kernel.org
Precedence: bulk

Split out from commit "NFS: Add fs_context support."

Rename cfg to ctx in nfs_init_server(), nfs_verify_authflavors(),
and nfs_request_mount().  No functional changes.
