Subject: [PATCH v2 6/9] mm: Demote warning message in vmemmap_verify() to debug level
Date: Thu, 14 Apr 2022 18:13:11 +0800 [thread overview]
Message-ID: <20220414101314.1250667-7-mawupeng1@huawei.com> (raw)
In-Reply-To: <20220414101314.1250667-1-mawupeng1@huawei.com>
From: Ma Wupeng <mawupeng1@huawei.com>
For a system only have limited mirrored memory or some numa node without
mirrored memory, the per node vmemmap page_structs prefer to allocate
memory from mirrored region, which will lead to vmemmap_verify() report
lots of warning message.
This patch demote the "potential offnode page_structs" warning messages
to debug level to avoid a very long print during bootup.
