[PATCH] memcg: Removed duplication detection for mem_cgroup_uncharge_swap

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



__mem_cgroup_uncharge_swap is only called in mem_cgroup_uncharge_swap,
if mem cgroup is disabled, __mem_cgroup_uncharge_swap cannot be called.
Therefore, there is no need to judge whether mem_cgroup is disabled or
not.
