There is no difference between 2.3.39 and 2.3.29 in this respect.

You are misunderstanding. I am talking about the parameters to
the function passed as 'get_info', *not* the create_proc_info_entry
function itself.
Note that get_info_t is of course *still* a function pointer type,
look at the typedef. *Those* arguments are the problem.
To repeat: this a real bug, and can only be fixed by solving the
real problem; *any* 'solution' using a type cast is broken.
