See http://www.infradead.org/rpr.html Sender: linux-xfs-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-xfs@vger.kernel.org Use the round_down macro, and use the size of the uint32 type we use in the callback that fills the buffer to make the code a little more clear - the size of it is always the same as int for platforms that Linux runs on.
