Ticket was cloned from Red Hat Bugzilla (product Red Hat Enterprise Linux 7): Bug 1577335

autofs_map_result_timeout() is called as a timed event to free the autofs map data is the cache lifetime is exceeded. If the data is freed earlier the timed event should be removed as well to avoid a double free issue.

Since talloc is used here the most easy way to achieve this is to allocate the timed event on the map object itself.
