Hi Roman, I noticed that you changed '#ifdef CONFIG_MEMCG' to '#ifdef CONFIG_MEMCG_V1'. However, it seems like the comments for the corresponding #else and #endif were not updated accordingly. It might be something like: diff --git a/include/linux/memcontrol.h b/include/linux/memcontrol.h index ba55ebd15354..796cfa842346 100644 --- a/include/linux/memcontrol.h +++ b/include/linux/memcontrol.h @@ -1883,7 +1883,7 @@ static inline void mem_cgroup_unlock_pages(void) rcu_read_unlock(); } -#else /* CONFIG_MEMCG */ +#else /* CONFIG_MEMCG_V1 */ static inline unsigned long memcg1_soft_limit_reclaim(pg_data_t *pgdat, int order, gfp_t gfp_mask, @@ -1922,6 +1922,6 @@ static inline bool mem_cgroup_oom_synchronize(bool wait) return false; } -#endif /* CONFIG_MEMCG */ +#endif /* CONFIG_MEMCG_V1 */ #endif /* _LINUX_MEMCONTROL_H */ --- Thanks, Lance
