From 50292ffdbbdbe52fb39296b7a966defa831ca0e4 Mon Sep 17 00:00:00 2001 From: Marco Elver Date: Mon, 5 Jul 2021 09:27:16 +0200 Subject: [PATCH] FROMLIST: kasan: fix build by including kernel.h The header relies on _RET_IP_ being defined, and had been receiving that definition via inclusion of bug.h which includes kernel.h. However, since f39650de687e that is no longer the case and get the following build error when building CONFIG_KASAN_HW_TAGS on arm64: In file included from arch/arm64/mm/kasan_init.c:10: ./include/linux/kasan.h: In function 'kasan_slab_free': ./include/linux/kasan.h:230:39: error: '_RET_IP_' undeclared (first use in this function) 230 | return __kasan_slab_free(s, object, _RET_IP_, init); Fix it by including kernel.h from kasan.h.
