Hmm, it seems it's already in net-next-2.6, sorry for the confusion.

    rcu: Disable lockdep checking in RCU list-traversal primitives
    
    The theory is that use of bare rcu_dereference() is more prone
    to error than use of the RCU list-traversal primitives.
    Therefore, disable lockdep RCU read-side critical-section
    checking in these primitives for the time being.  Once all of
    the rcu_dereference() uses have been dealt with, it may be time
    to re-enable lockdep checking for the RCU list-traversal
    primitives.
