Subject: [PATCH tip/core/rcu 0/21] Torture-test updates for v5.3
Date: Thu, 30 May 2019 08:16:50 -0700 [thread overview]
Message-ID: <20190530151650.GA422@linux.ibm.com> (raw)
Hello!
This series contains torture-test updates:
1. Make jitter.sh select from only online CPUs, courtesy of
Joel Fernandes.
2. Add cpu0 to the set of CPUs to add jitter, courtesy of Joel
Fernandes.
3. Add cond_resched() to forward-progress free-up loop.
4. Fix stutter_wait() return value and freelist checks.
5. Allow inter-stutter interval to be specified.
6. Make kvm-find-errors.sh and kvm-recheck.sh provide exit status.
7. Provide rudimentary Makefile.
8. Exempt tasks RCU from timely draining of grace periods.
9. Exempt TREE01 from forward-progress testing.
10. Give the scheduler a chance on PREEMPT && NO_HZ_FULL kernels.
11. Halt forward-progress checks at end of run.
12. Add trivial RCU implementation.
13. Tweak kvm options, courtesy of Sebastian Andrzej Siewior.
14. Capture qemu output.
15. Add function graph-tracing cheat sheet.
16. Run kernel build in source directory.
17. Make --cpus override idleness calculations.
18. Add --trust-make to suppress "make clean".
19. Dump trace buffer for callback pipe drain failures.
20. Suppress propagating trace_printk() warning.
21. Upper case solves the case of the vanishing NULL pointer.
Thanx, Paul
