Subject: [PATCH] KAsan: support including header from PBL
Date: Mon, 11 Sep 2023 14:15:24 +0200 [thread overview]
Message-ID: <20230911121524.2650416-1-a.fatoum@pengutronix.de> (raw)
It can be sometimes useful to add manual poisoning with KASAN to track
down errant accesses. This is complicated a bit, because some files are
build for both PBL and barebox proper. To make such debugging easier,
let's allow <linux/kasan.h> to be included from PBL code.
