[PATCH tip/core/rcu 0/8] rcu: add lockdep-based diagnostics to rcu_dereference()
Hello! This patch series adds lockdep-based checking to the rcu_dereference() primitive in order to flag misuses of RCU. The first three patches put the RCU infrastructure in place, while the last five use this infrastructure in the net, sched, vfs, radix-tree, and idr subsystems. There are very likely additional changes required.
