libosd: Use new blk_rq_map_kern
Now that blk_rq_map_kern will append the buffer onto the request we can use it easily for adding extra segments (eg. attributes) This patch is dependent on a block layer patch titled: [BLOCK] allow blk_rq_map_kern to append to requests Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
