Making the objects "black" means that they are completely ignored by
kmemleak and they are assumed not to contain any valid references.
Therefore they won't be scanned and many of the newly allocated objects
would be false positives.

You may want to make them "gray" and only those which were reported as
unreferenced, something like below:

if ((object->flags & OBJECT_REPORTED) && unreferenced_object(object))
