[RFC PATCH 0/2] tiny_rcu: simplify tiny_rcu

2014-11-28 Thread Lai Jiangshan
Hi, Paul These two patches use the special feture of the UP system: In UP, quiescent state == grace period. For rcu_bh, rcu_process_callbacks() == a bh == QS == GP so we can pass rcu_bh-QS and advance GP(and callbacks) in rcu_process_callbacks(). After doing so, rcu_bh_qs() is useless

[RFC PATCH 1/2] record rcu_bh quiescent state in RCU_SOFTIRQ

2014-11-28 Thread Lai Jiangshan
For rcu_bh in UP, rcu_process_callbacks() == a bh == QS == GP so we can pass rcu_bh-QS and advance GP(and callbacks) in rcu_process_callbacks(). After doing so, rcu_bh_qs() is useless since its work is handled by rcu_process_callbacks(). So we make it as empty-function and raise RCU_SOFTIRQ

[RFC PATCH 2/2] tiny_rcu: resched when call_rcu_sched() on idle_task

2014-11-28 Thread Lai Jiangshan
For rcu_sched in UP, context-switch = QS = GP, thus we can force a context-switch when call_rcu_sched() is happened on idle_task. After doing so, rcu_idle/irq_enter/exit() are useless, so we can simply make these functions empty. More important, this change does not change the functionality
