mm: list_lru: disable memcg_aware when cgroup.memory is set to "nokmem"
Actually, when using a boot time kernel option "cgroup.memory=nokmem", all
lru items are inserted to list_lru_node. But for those users who invoke
list_lru_init_memcg() to initialize list_lru, list_lru_memcg_aware()
returns true. And this brings unneeded operations related to memcg.
To make things more convenient, let's disable memcg_aware when
cgroup.memory is set to "nokmem".
