See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: target-devel@vger.kernel.org Replace the open coded offset calculation with the proper helper. This is an ABI change in that the -1 for a misaligned partition is properly propagated, which can be considered a bug fix and matches what is done on the whole device.
