From 1a984c4e8200e0e58bb316f14a4bebb28d32d15a Mon Sep 17 00:00:00 2001 From: Muchun Song Date: Mon, 14 Dec 2020 19:06:24 -0800 Subject: mm: memcontrol: remove unused mod_memcg_obj_state() Since commit 991e7673859e ("mm: memcontrol: account kernel stack per node") there is no user of the mod_memcg_obj_state(). So just remove it. Also rework type of the idx parameter of the mod_objcg_state() from int to enum node_stat_item.
