Subject: [PATCH 1/5] mm, memcg: remove unused functions
Date:   Thu, 29 Jul 2021 20:57:51 +0800

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.
