dump_object_infoPrint the kmemleak_object information. This function is used mainly for* debugging special cases when kmemleak operations. It must be called with* the object->lock held.

dump_entry_traceThe access to some variables in this macro is racy. We can't use atomic_t* here because all these variables are exported to debugfs. Some of them even* writeable. This is also the reason why a lock won't help much. But anyway,* the races are no big deal
