Hello! The following series disentangles kfree_rcu() from core RCU and also provides batching, all courtesy of Joel Fernandes: 1. Add basic support for kfree_rcu() batching. 2. Add kfree_rcu() performance tests. 3. Make kfree_rcu() use a non-atomic ->monitor_todo. 4. Add multiple in-flight batches of kfree_rcu() work. 5. Add support for debug_objects debugging for kfree_rcu(). 6. Remove kfree_rcu() special casing and lazy-callback handling. 7. Remove kfree_call_rcu_nobatch().
