    blkcg: minor updates around blkcg_policy_data · 81437648

    * Rename blkcg->pd[] to blkcg->cpd[] so that cpd is consistently used
      for blkcg_policy_data.
    
    * Make blkcg_policy->cpd_init_fn() take blkcg_policy_data instead of
      blkcg.  This makes it consistent with blkg_policy_data methods and
      to-be-added cpd alloc/free methods.
    
    * blkcg_policy_data->blkcg and cpd_to_blkcg() added so that
      cpd_init_fn() can determine the associated blkcg from
      blkcg_policy_data.
    
    v2: blkcg_policy_data->blkcg initializations were missing.  Added.
