I have put the V2 on the test over the weekend, so i will post it next week.
Yes, V2 will contain the debugobjects fix. Also i need to add tracing probe,
something like:

..
trace_rcu_invoke_kfree_bulk_callback();
kfree_bulk(bhead->nr_records, bhead->records);
..

probably it can be done as separate patch.

Thank you.
