[PATCH 0/4] cpuacct cleanup

[Glauber Costa <glommer@parallels.com>]

Hi,

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
