In this patch you add __memcpy etc, which will be used directly by modules if the above #if condition is met. I believe that EXPORT_SYMBOL() is necessary for __memcpy etc as well. One test for this would be compiling test_kasan.c as a module with KASAN_SANITIZE_test_kasan.o := n CONFIG_KASAN = y Patrick Daly -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
