Subject: [PATCH 5/9] block: use revalidate_disk_size in set_capacity_revalidate_and_notify
Date: Tue,  1 Sep 2020 17:57:44 +0200	[thread overview]
Message-ID: <20200901155748.2884-6-hch@lst.de> (raw)
In-Reply-To: <20200901155748.2884-1-hch@lst.de>

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.
