Ah, I found it:
http://kisskb.ellerman.id.au/kisskb/buildresult/14660585/log/
it's actually:
inlined from 'kasan_memcmp' at /kisskb/src/lib/test_kasan.c:897:2:
and
inlined from 'kasan_memchr' at /kisskb/src/lib/test_kasan.c:872:2:
I can send a patch doing the same as what [1] does for these cases too.
