No, kzalloc is not required. The memory area can come from any source. If you're interested in improving the debug situation, please stop trying to do something impossible (you can't track lifetime of random memory area without extra bookkeeping) try to find out why debugobj didn't detect it (did you even enable it? either via CONFIG_DEBUG_OBJECTS_ENABLE_DEFAULT or "debug_objects" boot param).
