[PATCH tip/core/rcu 0/4] SRCU updates for v4.21/v5.0
Hello! This series contains SRCU updates: 1. Fix kernel-doc missing notation, courtesy of Randy Dunlap. 2. Prevent __call_srcu() counter wrap with read-side critical section. 3. Lock srcu_data structure in srcu_gp_start(), fixing a an extremely rare but also extremely embarrassing concurrency bug, courtesy of Dennis Krein. 4. Use "ssp" instead of "sp" for srcu_struct pointer, in the hope that this prevents confusion about which lock is held.
