Subject: [PATCH-cpuset v8 0/2] Add Union-Find and use it to optimize cpuset

Hi Tejun,

Thank you for your suggestion. I agree with your point that it is indeed more
appropriate to place it within the cpuset structure, and I have already made
the modification. Additionally, I looked into the relevant modules of the
kernel, and it seems that the union-find data structure may have optimization
potential in network topology management and the Open vSwitch module. I will
further investigate this in the future.

Kindly review.

  Union-Find: add a new module in kernel library
  cpuset: use Union-Find to optimize the merging of cpumasks
