    blkcg: don't use blkg->plid in stat related functions · c1768268
    Tejun Heo authored
    blkg is scheduled to be unified for all policies and thus there won't
    be one-to-one mapping from blkg to policy.  Update stat related
    functions to take explicit @pol or @plid arguments and not use
    This is painful for now but most of specific stat interface functions
    will be replaced with a handful of generic helpers.
