This series contains SRCU updates: 1. Fix typos in __call_srcu() comment header. 2. Document that srcu_funnel_gp_start() implies srcu_funnel_exp_start(). 3. Add address of the first callback to rcutorture output to allow this output to show (lack of) forward progress. 4. Introduce srcu_read_{un,}lock_notrace() to avoid lockdep issues when applying SRCU to tracepoints.
