Subject: [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.

							Thanx, Paul
