set_timer_slack — set the allowed slack for a timer
| void set_timer_slack ( | struct timer_list * timer, | 
| int slack_hz ); | 
timerthe timer to be modified
slack_hzthe amount of time (in jiffies) allowed for rounding
   Set the amount of time, in jiffies, that a certain timer has
   in terms of slack. By setting this value, the timer subsystem
   will schedule the actual timer somewhere between
   the time mod_timer asks for, and that time plus the slack.
   
By setting the slack to -1, a percentage of the delay is used instead.
