Yeah, it would be nice if we avoid such code: blk_rq_map_user(q, rq, ...) bio = rq->bio blk_execute_rq(q, ... blk_rq_unmap_user(bio); I think that none of the users of blk_rq_map_user is interested in bio, the details of how kernel manage I/Os. At least, we can remove bio stuff in bsg if blk_rq_map_user and blk_rq_unmap_user take requests. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
