    blkcg: move blkio_group_conf->weight to cfq · 3381cb8d

    blkio_group_conf->weight is owned by cfq and has no reason to be
    defined in blkcg core.  Replace it with cfq_group->dev_weight and let
    conf setting functions directly set it.  If dev_weight is zero, the
    cfqg doesn't have device specific weight configured.
    
    Also, rename BLKIO_WEIGHT_* constants to CFQ_WEIGHT_* and rename
    blkio_cgroup->weight to blkio_cgroup->cfq_weight.  We eventually want
    per-policy storage in blkio_cgroup but just mark the ownership of the
    field for now.
