    blkcg: drop stuff unused after per-queue policy activation update · 3c96cb32

    * All_q_list is unused.  Drop all_q_{mutex|list}.
    * @for_root of blkg_lookup_create() is always %false when called from
      outside blk-cgroup.c proper.  Factor out __blkg_lookup_create() so
      that it doesn't check whether @q is bypassing and use the
      underscored version for the @for_root callsite.
    * blkg_destroy_all() is used only from blkcg proper and @destroy_root
      is always %true.  Make it static and drop @destroy_root.
