Subject: [PATCH-cpuset v7 0/2] Add Union-Find and use it to optimize cpuset

Hi Tejun,

I think I understand your point now. I have modified the Union-Find
implementation so that the allocation and deallocation are handled by the
user, providing only the initialization interface. Thanks for your
suggestion.

Kindly review.

Best Regards,
Xavier
