See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: ceph-devel@vger.kernel.org revalidate_disk_size just updates the block device size from the disk size. Thus calling it from virtblk_update_cache_mode doesn't actually do anything. Signed-off-by: Christoph Hellwig Acked-by: Stefan Hajnoczi Acked-by: Michael S.
