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(). This may
also someday allow system boot to bring CPUs online concurrently.
- 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.
- Improvements to RCU priority boosting, including changes from Neeraj
Upadhyay, Zqiang, and Alison Chaiken.
- Various fixes improving test robustness and debug information.
- Add tests for SRCU size transitions, further compress torture.sh
build products, and improve debug output.
- Miscellaneous fixes.
