SYNOPSIS

9       int mod_timer_pinned(struct timer_list * timer, unsigned long expires);
10

ARGUMENTS

12       timer
13           the timer to be modified
14
15       expires
16           new timeout in jiffies

DESCRIPTION

19       mod_timer_pinned is a way to update the expire field of an active timer
20       (if the timer is inactive it will be activated) and to ensure that the
21       timer is scheduled on the current CPU.
22
23       Note that this does not prevent the timer from being migrated when the
24       current CPU goes offline. If this is a problem for you, use CPU-hotplug
25       notifiers to handle it correctly, for example, cancelling the timer
26       when the corresponding CPU goes offline.
27
28       mod_timer_pinned(timer, expires) is equivalent to:
29
30       del_timer(timer); timer->expires = expires; add_timer(timer);
