Subject: [PATCH 0/9] RCU torture-test changes for v6.16

Hello!

The following series improves testing of SRCU-fast and SRCU up/down:

1.	Make srcu_lockdep.sh check kernel Kconfig.

2.	Make srcu_lockdep.sh check reader-conflict handling.

3.	Split out beginning and end from rcu_torture_one_read().

4.	Make torture.sh --do-rt use CONFIG_PREEMPT_RT.

5.	Add tests for SRCU up/down reader primitives.

6.	Pull rcu_torture_updown() loop body into new function.

7.	Comment invocations of tick_dep_set_task().

8.	Complain if an ->up_read() is delayed more than 10 seconds.

9.	Check for ->up_read() without matching ->down_read().

						Thanx, Paul
