See http://www.infradead.org/rpr.html Sender: linux-fsdevel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-fsdevel@vger.kernel.org Switch to use bdev_check_media_change instead of check_disk_change and call floppy_revalidate manually. Given that floppy_revalidate only deals with media change events, the extra call into ->revalidate_disk from bdev_disk_changed is not required either, so stop wiring up the method.
