From 33e22a832bdf79b032dd9d4ceac53fead5c2f552 Mon Sep 17 00:00:00 2001 From: Ye Liu <liuye(a)kylinos.cn&gt; Date: Wed, 3 Sep 2025 15:18:57 +0800 Subject: [PATCH] mem: rename variable for clarity in get_kmem_cache_slub_data() Rename 'cpu_slab_ptr' to 'cpu_slab_page_ptr' to better reflect that it holds a pointer to a page structure rather than a generic slab pointer. This improves code readability and consistency with related functions. No functional changes.
