Subject: [PATCH 2/4] mm/memcg: mem_cgroup_per_node is already set to 0 on allocation
Date: Tue, 11 Jan 2022 01:03:00 +0000	[thread overview]
Message-ID: <20220111010302.8864-2-richard.weiyang@gmail.com> (raw)
In-Reply-To: <20220111010302.8864-1-richard.weiyang@gmail.com>

kzalloc_node() would set data to 0, so it's not necessary to set it
again.
