See http://www.infradead.org/rpr.html Sender: linux-mmc-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-mmc@vger.kernel.org bd_contains is never NULL for an open block device. In addition ibd_bd is always set to a block device that was exclusively opened by the target code, so the holder is guranteed to be ib_dev as well.
