This patch is insufficient ... mem_cgroup_move_account() has the same bug.
Do we have similar issue mem_cgroup_move_account()?
void __mod_lruvec_state(struct lruvec *lruvec, enum node_stat_item idx,
int val)
{
/* Update node */
__mod_node_page_state(lruvec_pgdat(lruvec), idx, val);
the int val -> long val update happens as expected right?
