函数原型：static inline void __run_timers(struct timer_base *base)

返回类型：void

参数：

类型参数名称
struct timer_base *base
1745  如果非time_after_eq(jiffies, clk)则返回
1748  timer_base_lock_expiry(base)
1749  关闭本地中断，获取所要保护的运行队列（runqueue）的自旋锁（spinlock），为查找可运行进程做准备。( & lock)
1765  must_forward_clk = false
1767  当time_after_eq(jiffies, clk)循环
1769  levels等于collect_expired_timers(base, heads)
1770  clk自加
1772  当levels自减循环
1773  expire_timers(base, heads + levels)
1775  raw_spin_unlock_irq( & lock)
1776  timer_base_unlock_expiry(base)
