From a6def11b6dcde5d8f1fcc9e2c0ae71399432b62e Mon Sep 17 00:00:00 2001 From: Chengming Zhou Date: Tue, 23 Jan 2024 09:33:30 +0000 Subject: mm/slub: remove full list manipulation for non-debug slab Since debug slab is processed by free_to_partial_list(), and only debug slab which has SLAB_STORE_USER flag would care about the full list, we can remove these unrelated full list manipulations from __slab_free().
