mod_timer_pinned — modify a timer's timeout
int mod_timer_pinned (
struct timer_list * timer, unsigned long expires)
;
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 not allow the timer to be migrated to a different CPU.
mod_timer_pinned(timer, expires) is equivalent to:
del_timer(timer); timer->expires = expires; add_timer(timer);
