I see the same error messages after enabling CONFIG_KFENCE_KUNIT_TEST, but it doesn't go away after removing the patch below. That patch also seems to be completely unrelated to the error.
I also see the same problem in the mainline kernel. I suspect that something is wrong with CONFIG_KFENCE_KUNIT_TEST.
