Hi Ross

Thanks for the info.
I actually did look into the KPATCH_IGNORE_FUNCTION code. But.. I
somehow ended up having this:

void *__kpatch_ignore_func_##_fn __section(.kpatch.ignore.functions) = (#_fn);

Which apparently caused the symbol not being a function type, but a string(?).

You've got a single # before _fn which causes stringification of the macro parameter. Therefore the symbol became a string and not a function.
