hi,

    DPRINTK("do_blk_req %p: cmd %p, sec %llx, "
            "(%u/%li) buffer:%p [%s]\n",
            req, req->cmd, (long long)req->sector,
            req->current_nr_sectors,
            req->nr_sectors, req->buffer,
            rq_data_dir(req) ? "write" : "read");

this statement is located in the blkfront.c file ,in the do_blkif_request(request_queue_t *rq) function. i know DPRINTK is used for debug only. if i want to see the DPRINTK message , how could i do? that's how to open the debug mode to compile xen source code? Thanks!
