From 4d0e3230a56a75bf26d74b3f4b6cb05a0e9fae60 Mon Sep 17 00:00:00 2001 From: Qian Cai Date: Mon, 23 Sep 2019 15:37:19 -0700 Subject: mm/memcontrol.c: fix a -Wunused-function warning mem_cgroup_id_get() was introduced in commit 73f576c04b94 ("mm:memcontrol: fix cgroup creation failure after many small jobs"). Later, it no longer has any user since the commits, 1f47b61fb407 ("mm: memcontrol: fix swap counter leak on swapout from offline cgroup") 58fa2a5512d9 ("mm: memcontrol: add sanity checks for memcg->id.ref on get/put") so safe to remove it.
