--- Comment #3 from William Cohen <wcohen at redhat dot com> ---
This issue looks to be related to the upstream change in the kernel for
kallsyms_on_each_symbol:

Precedes: v6.4-rc1

    kallsyms: Delete an unused parameter related to
{module_}kallsyms_on_each_symbol()

    The parameter 'struct module *' in the hook function associated with
    {module_}kallsyms_on_each_symbol() is no longer used. Delete it.

new kernels have in include/linux/kallsyms.h:

int kallsyms_on_each_symbol(int (*fn)(void *, const char *, unsigned long),
                            void *data);


old kernels (<6.4) in include/linux/kallsyms.h:

int kallsyms_on_each_symbol(int (*fn)(void *, const char *, struct module *,
                                      unsigned long),
                            void *data);
