The following is a piece of code from the latter half of
schedule_timeout, in kernel/sched.c. Is it possible that
schedule_timeout could return an incorrect value, if the jiffy value
wraps between the first and last lines shown below.
expire = timeout + jiffies;
init_timer(&timer);
timer.expires = expire;
timer.data = (unsigned long) current;
timer.function = process_timeout;
add_timer(&timer);
schedule();
del_timer_sync(&timer);
timeout = expire - jiffies;
