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().
