    blkcg: move statistics update code to policies · 629ed0b1
    Tejun Heo authored
    As with conf/stats file handling code, there's no reason for stat
    update code to live in blkcg core with policies calling into update
    them.  The current organization is both inflexible and complex.
    
    This patch moves stat update code to specific policies.  All
    blkiocg_update_*_stats() functions which deal with BLKIO_POLICY_PROP
    stats are collapsed into their cfq_blkiocg_update_*_stats()
    counterparts.  blkiocg_update_dispatch_stats() is used by both
    policies and duplicated as throtl_update_dispatch_stats() and
    cfq_blkiocg_update_dispatch_stats().  This will be cleaned up later.
