Hello!
This series contains updates for RCU's expedited grace-period facility:
1. Make expedited RCU-sched grace period immediately detect idle.
2. Make expedited RCU-preempt stall warnings count accurately.
3. Make cond_resched_rcu_qs() supply RCU-sched expedited QS.
4. Fix synchronize_rcu_expedited() header comment.
5. Add event tracing definitions for expedited grace periods.
6. Add funnel-locking tracing for expedited grace periods.
7. Add expedited-grace-period event tracing.
8. Remove expedited GP funnel-lock bypass.
9. Force boolean subscript for expedited stall warnings.
10. Shorten expedited_workdone* to exp_workdone*.
11. Enforce expedited-GP fairness via funnel wait queue.
12. Add exp_funnel_lock() fastpath for new funnel wait queue.
13. Consolidate expedited GP code into rcu_exp_wait_wake().
14. Consolidate expedited GP tracing into rcu_exp_gp_seq_snap().
15. Consolidate expedited GP code into exp_funnel_lock().
16. Overlap wakeups with next expedited grace period.
Thanx, Paul
