MIME-Version: 1.0 Content-Disposition: inline Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Message-Id: <200901290005.59200.rusty@rustcorp.com.au> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org OK, the rest of this series was really intellectual masturbation. This patch just takes off the SHF_ALLOC flag on __versions so we don't keep them around after module load.
