void (*fn
unsigned longbaseclk
1382  count等于抢占计数值
1401  lock_map_acquire( & lockdep_map)
1403  mer_expire_entry - called immediately before the timer callback*@timer: pointer to struct timer_list* Allows to determine the timer latency.
1404  fn(timer)
1405  mer_expire_exit - called immediately after the timer callback returns*@timer: pointer to struct timer_list* When used in combination with the timer_expire_entry tracepoint we can* determine the runtime of the timer callback function.
1407  lock_map_release( & lockdep_map)
1409  如果count不等于抢占计数值则
1410  WARN_ONCE(1, "timer: %pS preempt leak: %08x -> %08x\n", fn, count, 抢占计数值)
1418  设置抢占计数
