Subject: [PATCH] kasan: export kasan_poison
Date: Mon, 25 Jan 2021 12:28:13 +0100 [thread overview]
Message-ID: <20210125112831.2156212-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The unit test module fails to build after adding a reference
to kasan_poison:
ERROR: modpost: "kasan_poison" [lib/test_kasan.ko] undefined!
Export this symbol to make it available to loadable modules.
Fixes: b9b322c2bba9 ("kasan: add match-all tag tests")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
