[PATCH 08/19] xsysace: use bdev_check_media_change

From: Christoph Hellwig
Date: Tue Sep 08 2020 - 15:44:35 EST


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.
