    Subject[PATCH 0/4] cpuacct cleanup

    Leaving aside all the hierarchy walk discussion, I tried to come up
    with a series that concentrates only the basic points of it all.
    I think we benefit from having it independently of the rest of the work:
    in general (comments on the specifics welcome) cpuacct is made more naturally
    integrated with the scheduler, and the statistics it collects are now exactly
    the same as the system-wide ones for the root cgroup case. I think quite similar
    can be done with cpuusage by associating the root cgroup with the main runqueues,
    but this here is just me scratching my own itches - we can do it later.

    Please let me know if this is acceptable.

    Glauber Costa (4):
    Change cpustat fields to an array.
    Reuse cgroup's parent pointer
    Move part of cpuacct code
    cpuacct.stat: re-use scheduler statistics for the root cgroup
