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?
Yes.
Kindly review.

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

The patch series looks good to me. However, it is a still major change
in the domain generation algorithm and it is too late for v6.11. I would
also like it to spend more time in linux-next as I don't have a good set
of cgroup v1 test. I will support merging this for v6.12.
