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 In preparation for moving the ioend structure to common code we need to get rid of the xfs-specific xfs_trans type. Just make it a file system private void pointer instead. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Chinner Reviewed-by: Darrick J.
