This is v2. This small change tends to improve even more the slow path of kvfree_rcu_mightsleep() API. It is hit when a low memory condition occurs which leads us into two options: a) check if a GP is already passed for freed object; b) if not, initialize and wait for completion of a new GP.
The differecne between v1 -> v2: - Drop "Support dynamic rcu_head for single argument objects" patch; - Use cond_synchronize_rcu_full() in a slow path.
