Subject[PATCH rcu 0/7] RCU-related lockdep changes for v6.4

This series enables deadlock detection for srcu_read_lock() vs
synchronize_srcu().

Again, my first time helping prepare PR, so please take a careful look
and yell at me if there is something wrong. Thanks a lot!

You will also be able to find the series at:
