NAME
       mod_timer_pinned - modify a timer's timeout

SYNOPSIS
       int mod_timer_pinned(struct timer_list * timer, unsigned long expires);

ARGUMENTS
       timer
	   the timer to be modified

       expires
	   new timeout in jiffies

DESCRIPTION
       mod_timer_pinned is a way to update the expire field of an active timer
       (if the timer is inactive it will be activated) and to ensure that the
       timer is scheduled on the current CPU.

       Note that this does not prevent the timer from being migrated when the
       current CPU goes offline. If this is a problem for you, use CPU-hotplug
       notifiers to handle it correctly, for example, cancelling the timer
       when the corresponding CPU goes offline.

       mod_timer_pinned(timer, expires) is equivalent to:

       del_timer(timer); timer->expires = expires; add_timer(timer);
