[PATCH -next] mm/memcontrol.c: replace cgroup_memory_nokmem with mem_cgroup_kmem_disabled()

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

 



mem_cgroup_kmem_disabled() checks whether the kmem accounting is off.
Therefore, replace cgroup_memory_nokmem with mem_cgroup_kmem_disabled(),
which is the same work in percpu.c and slab_common.c.
