[PATCH 1/5] mm, memcg: remove unused functions
From: Miaohe Lin <linmiaohe@huawei.com>
Date: 2021-07-29 12:57:59
Also in:
linux-mm, lkml
Subsystem:
control group - memory resource controller (memcg), the rest · Maintainers:
Johannes Weiner, Michal Hocko, Roman Gushchin, Shakeel Butt, Linus Torvalds
Since commit 2d146aa3aa84 ("mm: memcontrol: switch to rstat"), last user
of memcg_stat_item_in_bytes() is gone. And since commit fa40d1ee9f15 ("mm:
vmscan: memcontrol: remove mem_cgroup_select_victim_node()"), only the
declaration of mem_cgroup_select_victim_node() is remained here. Remove
them.
