[PATCH 5/9] block: use revalidate_disk_size in set_capacity_revalidate_and_notify

From: Christoph Hellwig
Date: Tue Sep 01 2020 - 11:58:34 EST


Only virtio_blk and xen-blkfront set the revalidate argument to true,
and both do not implement the ->revalidate_disk method. So switch
to the helper that just updates the size instead.
