Hi Tejun,

That's the reason why I've reordered (as per your request) the series
to have all the core and non-cgroup related bits at the beginning.

There are a couple of patches at the end of this series which can be
anticipated but, apart from those, the cgroup code is very well
self-contained within patches 7-12.

Indeed, this is what I worked on since you pointed out in v1 that
there must be a meaningful non-cgroup API and that's what we have
since v2.

IMHO, developing the cgroup interface on top of the core bits is quite
important to ensure that we have effective data structures and
implementation which can satisfy both worlds.

My question is: IF the scheduler maintainers are going to be happy
with the overall design for the core bits, are you happy to start the
review of the cgroups bits before the core ones are (eventually) merged?

Cheers,
Patrick
