[PATCH 1/5] lib/union_find: Add EXPORT_SYMBOL() for uf_find() and uf_union()

From: Kuan-Wei Chiu
Date: Sat Oct 05 2024 - 17:50:15 EST


Add EXPORT_SYMBOL() for the uf_find() and uf_union() functions to allow
kernel modules, including the KUnit tests for the Union-Find data
structure, to use these functions. This enhances the usability of the
Union-Find implementation in a modular context, facilitating easier
testing and integration.
