Hi,

>From the error which you've pasted:

> > error: ‘struct module’ has no member named ‘target_list’

it looks like 'target_list' is not visible in 'struct module' in your kernel 
definition. I've checked 4.19.8 kernel source and it looks like, this situation 
is only possible if you compile kernel without CONFIG_MODULE_UNLOAD:

https://elixir.bootlin.com/linux/v4.19.8/source/include/linux/module.h#L463

Can you confirm this is the case for your kernel config?

Thanks,
Adam
