[PATCH 0/5] Enhance Union-Find with KUnit tests and optimization improvements

From: Kuan-Wei Chiu
Date: Sat Oct 05 2024 - 17:50:03 EST


This patch series adds KUnit tests for the Union-Find implementation
and optimizes the path compression in the uf_find() function to achieve
a lower tree height and improved efficiency. Additionally, it modifies
uf_union() to return a boolean value indicating whether a merge
occurred, enhancing the process of calculating the number of groups in
the cgroup cpuset.

Regards,
Kuan-Wei
