Subject: [PATCH -mmotm] arm64: skip kmemleak for KASAN again
Date: Tue, 25 Dec 2018 21:05:50 -0500 [thread overview]
Message-ID: <20181226020550.63712-1-cai@lca.pw> (raw)
Due to 871ac3d540f (kasan: initialize shadow to 0xff for tag-based
mode), kmemleak is broken again with KASAN. It needs a similar fix
from e55058c2983 (mm/memblock.c: skip kmemleak for kasan_init()).
