add_timer — start a timer
void add_timer ( | struct timer_list * timer); |
The kernel will do a ->function(->data) callback from the timer interrupt at the ->expires point in the future. The current time is 'jiffies'.
The timer's ->expires, ->function (and if the handler uses it, ->data) fields must be set prior calling this function.
Timers with an ->expires field in the past will be executed in the next timer tick.
