Subject: [RESEND PATCH v2 01/12] mm: memcontrol: fix NR_ANON_THPS account
Date: Sun, 6 Dec 2020 18:14:40 +0800 [thread overview]
Message-ID: <20201206101451.14706-2-songmuchun@bytedance.com> (raw)
In-Reply-To: <20201206101451.14706-1-songmuchun@bytedance.com>
The unit of NR_ANON_THPS is HPAGE_PMD_NR already. So it should inc/dec
by one rather than nr_pages.
Fixes: 468c398233da ("mm: memcontrol: switch to native NR_ANON_THPS counter")
