[PATCH tip/core/rcu 0/28] Torture-test scripting updates for v5.13

[Paul E. McKenney]

Hello!

This series contains updates to the torture-test scripting, perhaps most
notably the addition of kvm-again.sh, which allows rerunning an earlier
test without having to rebuild all the kernels.

1.	Don't rerun failed rcutorture builds.

2.	Allow 1G of memory for torture.sh kvfree testing.

3.	Provide bare-metal modprobe-based advice.

4.	Improve readability of the testid.txt file.

5.	Disable verbose torture-test output.

6.	Disable verbose torture-test output.

7.	Move build/run synchronization files into scenario directories.

8.	Use file-based protocol to mark batch's runs complete.

9.	Use "jittering" file to control jitter.sh execution.

10.	Eliminate jitter_pids file.

11.	Reverse jittering and duration parameters for jitter.sh.

12.	Abstract jitter.sh start/stop into scripts.

13.	Record TORTURE_KCONFIG_GDB_ARG in qemu-cmd.

14.	Extract kvm-test-1-run-qemu.sh from kvm-test-1-run.sh.

15.	Record jitter start/stop commands.

16.	Record kvm-test-1-run.sh and kvm-test-1-run-qemu.sh PIDs.

17.	Remove no-mpstat error message.

18.	Rename SRCU-t and SRCU-u to avoid lowercase characters.

19.	Make upper-case-only no-dot no-slash scenario names official.

20.	De-capitalize TORTURE_SUITE.

21.	Create a "batches" file for build reuse.

22.	Add kvm-again.sh to rerun a previous torture-test.

23.	Add --duration argument to kvm-again.sh.

24.	Make kvm-transform.sh update jitter commands.

25.	Make TORTURE_TRUST_MAKE available in kvm-again.sh environment.

26.	Print proper vmlinux path for kvm-again.sh runs.

27.	Consolidate qemu-cmd duration editing into kvm-transform.sh.

28.	Fix kvm.sh --datestamp regex check.

						Thanx, Paul
