From 9660ecaa79ce5c068aa3138ca7e29a9402f284ed Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Mon, 28 Jun 2021 19:41:31 -0700 Subject: [PATCH] mm/page_alloc: switch to pr_debug Having such debug messages in the dmesg log may confuse users. Therefore restrict debug output to cases where DEBUG is defined or dynamic debugging is enabled for the respective code piece.
