941  如果set if tracing memory operations is enabled 则
942  Create the metadata (struct kmemleak_object) corresponding to an allocated* memory block and add it to the object_list and object_tree_root.
943  Any surplus references (object already gray) to 'ptr' are passed to* 'excess_ref'. This is used in the vmalloc() case where a pointer to* vm_struct may be used as an alternative reference to the vmalloc'ed object* (see free_thread_stack()).
