From abd62377c0064302df680ab33f4c05290ba24af8 Mon Sep 17 00:00:00 2001 From: Ma Wupeng Date: Tue, 14 Jun 2022 17:21:54 +0800 Subject: [PATCH] mm: Limit warning message in vmemmap_verify() to once 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 change the frequency of "potential offnode page_structs" warning messages to only once to avoid a very long print during bootup.
