# \[PATCH 07/19\] swim3: use bdev\_check\_media\_changed - From: Christoph Hellwig \ - Date: 2020-09-02 14:40:20 - List: linux-raid - Page: https://ratatoskr.run/linux-raid/2020/09/187816 - Thread: https://ratatoskr.run/linux-block/2020/09/187819/t.md ```text Switch to use bdev_check_media_changed 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.
