The name_show symbol is not the best choise, because it often appears only three times on s390 in kallsyms, with two of them having module annotations [mdev] and [i2c_core].
Switch to init_once which has many more duplicate instances all in vmlinux, making it a more reliable non-unique symbol for testing kprobe registration failure.
