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.
