Hello! This series contains performance improvements and locktorture testing for percpu-rwsem: 1. Add rtmutex torturing to locktorture, courtesy of Davidlohr Bueso. 2. Add exports to allow locktorture to be built as a module. 3. Add torture tests for percpu-rwsem. 4. Consolidate cond_resched_rcu_qs() into stutter_wait(). 5. Create rcu_sync infrastructure, courtesy of Oleg Nesterov. 6. Simplify rcu_sync using new rcu_sync_ops structure, courtesy of Oleg Nesterov. 7. Add CONFIG_PROVE_RCU checks for rcu_sync, courtesy of Oleg Nesterov. 8. Introduce rcu_sync_dtor(), courtesy of Oleg Nesterov. 9. Make percpu_free_rwsem() after kzalloc() safe, courtesy of Oleg Nesterov. 10. Make percpu-rwsem make use of rcu_sync, courtesy of Oleg Nesterov. 11. Fix the comments outdated by rcu_sync, courtesy of Oleg Nesterov. 12. Clean up the lockdep annotations in percpu_down_read(), courtesy Peter Zijlstra and of Oleg Nesterov. 13. Cleanup the CONFIG_PROVE_RCU checks, courtesy of Oleg Nesterov.
