函数名称：Print 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.

函数原型：static void dump_object_info(struct kmemleak_object *object)

返回类型：void

名称描述
lookup_objectLook-up a memory block metadata (kmemleak_object) in the object search* tree based on a pointer value. If alias is 0, only values pointing to the* beginning of the memory block are allowed. The kmemleak_lock must be held* when calling this function.
create_objectCreate the metadata (struct kmemleak_object) corresponding to an allocated* memory block and add it to the object_list and object_tree_root.
add_scan_areaAdd a scanning area to the object. If at least one such area is added,* kmemleak will only scan these ranges rather than the whole memory block.
kmemleak_scanScan data sections and all the referenced memory blocks allocated via the* kernel's standard allocators. This function must be called with the* scan_mutex held.
