From 3a6f33d86baa8103c80f62edd9393e9f7bf25d72 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Cl=C3=A9ment=20L=C3=A9ger?= Date: Tue, 8 Nov 2022 10:43:22 +0100 Subject: [PATCH] mm/kmemleak: use %pK to display kernel pointers in backtrace MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, %p is used to display kernel pointers in backtrace which result in a hashed value that is not usable to correlate the address for debug. Use %pK which will respect the kptr_restrict configuration value and thus allow to extract meaningful information from the backtrace.
