Subject: [EXTERNAL] [PATCH] test/graph: fix graph autotest second test failure

 

Start dpdk-test, execute the graph_autotest test command for the first time, the result is successful, and then test again, the result is always failing, modify this problem to make this test command idempotent. Signed-off-by: Huichao cai <chcchc88@ 163. com>

I think cloned nodes are not being added to any graph, so, not being freed. So, we are seeing this issue.
Instead of suppressing the errors, could you create a dummy graph and add the nodes to graph and call graph destroy.
This will free the cloned nodes and we don’t see this problem.
