mem_cgroup_id_get() was introduced in commit 73f576c0 ("mm:memcontrol: fix cgroup creation failure after many small jobs"). Later, it no longer has any user since the commits, 1f47b61f ("mm: memcontrol: fix swap counter leak on swapout from offline cgroup") 58fa2a55 ("mm: memcontrol: add sanity checks for memcg->id.ref on get/put") so safe to remove it.
