    Subject[RFC][PATCH 0/6] using lockdep to validate rcu usage
    This patch set uses lockdep to validate rcu usage.

    It annotates rcu_read_{,un}lock{,_bh}() to catch imbalances. And further uses
    that information to establish a proper context for rcu_dereference().

    separate rcu_dereference() from the locking model.
