This has changed: CPUs routinely post requests for future grace periods in order to promote power efficiency and reduce OS jitter with minimal impact on grace-period latency. This commit therefore updates cpu_needs_another_gp() to invoke rcu_future_needs_gp() instead of rcu_nocb_needs_gp(). The latter is no longer used, so is now removed. This commit also adds tracing for the irq_work_queue() wakeup case. Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett --- Reading git-diff-tree failed
