See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: ceph-devel@vger.kernel.org The update_bdev argument is always set to true, so remove it. Also rename the function to the slighly less verbose set_capacity_and_notify, as propagating the disk size to the block device isn't really revalidation.
