From 7714304f3ba16af9cf52952d182d031d04b62d6d Mon Sep 17 00:00:00 2001 From: Hui Su Date: Mon, 14 Dec 2020 19:03:47 -0800 Subject: mm/slab_common.c: use list_for_each_entry in dump_unreclaimable_slab() dump_unreclaimable_slab() acquires the slab_mutex first, and it won't remove any slab_caches list entry when itering the slab_caches lists. Thus we do not need list_for_each_entry_safe here, which is against removal of list entry.
