Hello!
This series fixes a bug in which an RCU-priority-boosted task can stay
boosted for some time after it has exited its RCU read-side critical
section. This bug arose during the RCU flavor consolidation effort.
The patches are as follows:
1. Expedite deboost in case of deferred quiescent state.
2. Make TREE03 use real-time tree.use_softirq setting.
3. Run rcuo kthreads at elevated priority in CONFIG_RCU_BOOST
kernels.
4. Fix testing of RCU priority boosting.
Thanx, Paul
