Subject[PATCH v3 4/6] mm: Demote warning message in vmemmap_verify() to debug level
From: Ma Wupeng <>

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() in
vmemmap_populate_basepages() 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.
