raw_spin_lock_irqsave( & Protection of the PI data structures: , flags)

111

rq等于task_rq(p)

112

raw_spin_lock( & 运行队列锁)

如果此条件成立可能性大(为编译器优化)(rq == task_rq(p) && !task_on_rq_migrating(p))则

131

rq_pin_lock(rq, rf)

132

返回:rq

134

raw_spin_unlock( & 运行队列锁)

135

raw_spin_unlock_irqrestore( & Protection of the PI data structures: , flags)

137

当此条件成立可能性小(为编译器优化)(task_on_rq_migrating(p))循环
