# \[PATCH 08/19\] xsysace: use bdev\_check\_media\_change - From: Christoph Hellwig \ - Date: 2020-09-02 14:47:47 - List: linux-raid - Page: https://ratatoskr.run/linux-raid/2020/09/187826 - Thread: https://ratatoskr.run/linux-block/2020/09/187819/t.md ```text Switch to use bdev_check_media_change instead of check_disk_change and call ace_revalidate_disk manually. Given that ace_revalidate_disk 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.
