From 14a405c3a933ce261147a60dfb8bf586b45ec9de Mon Sep 17 00:00:00 2001 From: Lu Jialin Date: Sat, 19 Aug 2023 08:13:02 +0000 Subject: memcg: remove duplication detection for mem_cgroup_uncharge_swap __mem_cgroup_uncharge_swap is only called in mem_cgroup_uncharge_swap, if mem cgroup is disabled, __mem_cgroup_uncharge_swap cannot be called. Therefore, there is no need to judge whether mem_cgroup is disabled or not.
