Sashiko basically complains about that this might make dump_stack(), panics, and oopses useless on systems without KALLSYMS which is typical on embedded systems. IMHO, it is a good point. What about using default_pointer() resp. %p as the fallback? It would allow to see the pointers with "no_hash_pointers" kernel parameter. Best Regards, Petr
