Therefore, refcount related to the search iterators should be cleaned\nup after the search is complete.\n\nUse the __free() cleanup macro to ensure the refcount is decremented when the\ntemporary pointer goes out of scope.\n\nAdditionally, increment the refcount when caching a root pointer. This ensures\nthe in-use refcount is separate from the temporary search refcounting.\n\nFinally, drop the redundant \"root = NULL\" before the second search loop. The\npci_get_class() iterator always decrements the refcount of its \"from\"\nargument, so the first loop can only fall through with \"root\" already NULL."
