See http://www.infradead.org/rpr.html Sender: linux-block-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-block@vger.kernel.org Switch to use bdev_check_media_changed instead of check_disk_change and call idecd_revalidate_disk manually. Given that idecd_revalidate_disk only re-reads the TOC, and we already do the same at probe time, the extra call into ->revalidate_disk from bdev_disk_changed is not required either, so stop wiring up the method.
