    Linus Torvalds authored
    Pull cgroup updates from Tejun Heo:
     "The bulk of changes are cleanups and preparations for the upcoming
      kernfs conversion.
    
       - cgroup_event mechanism which is and will be used only by memcg is
         moved to memcg.
    
       - pidlist handling is updated so that it can be served by seq_file.
    
         Also, the list is not sorted if sane_behavior.  cgroup
         documentation explicitly states that the file is not sorted but it
         has been for quite some time.
    
       - All cgroup file handling now happens on top of seq_file.  This is
         to prepare for kernfs conversion.  In addition, all operations are
         restructured so that they map 1-1 to kernfs operations.
    
       - Other cleanups and low-pri fixes"
