Subject: [PATCH-cpuset v11 0/2] Add Union-Find and use it to optimize cpuset

Hi all,

Based on Michal's suggestion, the following changes were made:
1. Changed Union-Find to union-find in all places except the title.
2. Optimized the logic of the uf_union function.
3. Modified places where csa[i]->node.parent was used directly.

To Longman,
Regarding the modifications for supporting cpuset merging in both cgroup
v1 and v2, do you mean that you will continue to complete them after my
patch is merged?

Kindly review.

Xavier (2):
  Union-Find: add a new module in kernel library
  cpuset: use Union-Find to optimize the merging of cpumasks
