Subject: [PATCH v4 3/8] mm: memcg: account memory used for memcg vmstats and lruvec stats
Date: Wed,  1 May 2024 10:26:12 -0700	[thread overview]
Message-ID: <20240501172617.678560-4-shakeel.butt@linux.dev> (raw)
In-Reply-To: <20240501172617.678560-1-shakeel.butt@linux.dev>

From: Roman Gushchin <roman.gushchin@linux.dev>

The percpu memory used by memcg's memory statistics is already accounted.
For consistency, let's enable accounting for vmstats and lruvec stats
as well.
