Subject: Re: [PATCH rcu 0/11] Torture-test updates

Hello!

This series contains torture-test updates:

1.	Add get_torture_init_jiffies() for test-start time.

2.	Add a test_boost_holdoff module parameter.

3.	Include grace-period sequence numbers in failure/close-call.

4.	Expand failure/close-call grace-period output.

5.	Trace expedited grace-period numbers in hexadecimal.

6.	Add ftrace-compatible timestamp to GP# failure/close-call output.

7.	Make cur_ops->format_gp_seqs take buffer length.

8.	Move RCU_TORTURE_TEST_{CHK_RDR_STATE,LOG_CPU} to bool.

9.	Complain when invalid SRCU reader_flavor is specified.

10.	Add FORCE_NEED_SRCU_NMI_SAFE Kconfig for testing.

11.	Make SRCU lockdep testing use srcu_read_lock_nmisafe().

Changes since v1:

o	Fix "segement" typo in commit log.

						Thanx, Paul
