This pull request contains the following branches: exp.2022.02.24a: Contains a fix for idle detection from Neeraj Upadhyay and missing access marking detected by KCSAN. fixes.2022.02.14a: Miscellaneous fixes. rcu_barrier.2022.02.08a: Reduces coupling between rcu_barrier() and CPU-hotplug operations, so that rcu_barrier() no longer needs to do cpus_read_lock(). This may also someday allow system boot to bring CPUs online concurrently. rcu-tasks.2022.02.08a: Enable more aggressive movement to per-CPU queueing when reacting to excessive lock contention due to workloads placing heavy update-side stress on RCU tasks. rt.2022.02.01b: Improvements to RCU priority boosting, including changes from Neeraj Upadhyay, Zqiang, and Alison Chaiken. torture.2022.02.01b: Various fixes improving test robustness and debug information. torturescript.2022.02.08a: Add tests for SRCU size transitions, further compress torture.sh build products, and improve debug output. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmIusb0THHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jAklD/9VXLK7crcg2YeRXUIg1IOdnancsVCV MNtTfxNYqYIis+W2UfuHKuQu2yEXF5fihdY0J9TQv0byHsprp6FIZT+i1An4Ukgd 0vyHjd/DaIKgs2txsB1DjhlatWlJUfQuBwhtNUkpYFLFwKdCI1l813bPbNlL+GiL p0ZejVMpBC5HgE6sDOtaaQSAB+AEUp+Lgr+yaG/On8hfzwWFKO8KldxhiKY9n07v SNDfKDgXB+80hx4RBVGbkuogV3s9brFULoNRXJy7Uf79DtiY09uazhhA3G0TjO34 zGwmF91dqsXDF/Uz8g4aZO0xYRXUchOrsQ5lgO/GhTVbM9I0wWlMHEk/8WHyBJkU vlXOMuwzBc9/5uwZE3rnkA4a3nkXhPQjLlCr+/I7A/7Vsv9IBW9WSlgMvUN0Qf4S XAwTnIqfErnR60a+L0+HRr5kIV5VoXcxqI/Nv0/4/BMLRubS/c7cYjOTxXNJL9SU 50pv5vty9xk3HSpuz0JAOyLf+PUT773uUQhFr5xCBSCVqbAm5WFg6hWPAgrN/tUS wstBc0wlA73rKVJxeLDQwHc/oT1zTUEzswVZITQ5zLHK0t0GbeR6QHccsdeaJyTe DisX+66A6YQrEuJmx5xUZqjYHqtYLDOBTbHA3ZwQmvjKu8ibWZ8Fg9ioURLCS4bF +FVkp/5KdcAN9w== =ljVY -----END PGP SIGNATURE----- Merge tag 'rcu.2022.03.13a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU updates from Paul McKenney: - Fix idle detection (Neeraj Upadhyay) and missing access marking detected by KCSAN. - Reduce coupling between rcu_barrier() and CPU-hotplug operations, so that rcu_barrier() no longer needs to do cpus_read_lock().
