[PATCH rcu 0/7] Torture-test updates for v5.15

[Paul E. McKenney]

Hello!

This series contains updates to the in-kernel torture tests:

1.	Add measurement of clock readout.

2.	Preempt rather than block when testing task stalls.

3.	Console output claims too few grace periods, courtesy of
	"Jiangong.Han".

4.	Mark statistics data races.

5.	Count lock readers.

6.	Add RPC-like IPI tests.

7.	Avoid NULL pointer exception on early exit.

						Thanx, Paul
