The patch titled Subject: mm: memcontrol: remove unused mod_memcg_obj_state() has been removed from the -mm tree. Its filename was mm-memcontrol-remove-unused-mod_memcg_obj_state.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Muchun Song <songmuchun@xxxxxxxxxxxxx> 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(). This patch just remove it. Also rework type of the idx parameter of the mod_objcg_state() from int to enum node_stat_item.
