Issue
When I use add_timer&del_timer on linux kernel developing, the words "active", "inactive" and "deactivate" are often shown in function usage explanation. What does "active" mean ?
Does it mean: The time of which the value is assigned to timer_list->expires is reached, so the timer is active. Or does it mean that the timer is active immediately after add_timer or mod_timer is returned.
Solution
An inactive timer won't fire. You can activate it with mod_timer
. Deactivating is possible with del_timer
.
