| |
Hello!
This series contains general fixes:
1. Make cond_resched() provide RCU quiescent state, which finally avoids degrading performance.
2. Use timer as backstop for NOCB deferred wakeups.
3. Simplify RCU Kconfig by driving TASKS_RCU directly off of PREEMPT.
4. Create reasonable API for do_exit() TASKS_RCU processing.
5. Add TPS() to event-traced strings.
6. Move rcu.h to new trivial-function style.
7. Add event tracing to ->gp_tasks update at GP start.
8. Add idle swait variants which don't contribute to load average, courtesy of Luis R. Rodriguez.
9. Use idle versions of swait to make idle-hack clear, courtesy of Luis R. Rodriguez.
10. Add TPS() protection for _rcu_barrier_trace strings.
11. Set disable_rcu_irq_enter on rcu_eqs_exit(), courtesy of Masami Hiramatsu.
12. Add assertions verifying blocked-tasks list.
13. Make rcu_idle_enter() rely on callers disabling irqs, courtesy of Peter Zijlstra.
14. Add warning to rcu_idle_enter() for irqs enabled.
15. Remove exports from rcu_idle_exit() and rcu_idle_enter().
Thanx, Paul
