Hi, I neither know the semantics of the timer_list nor how to use seq_file correctly. What happens is that timer_list_next will only be called once. This means that iter->cpu will never be increased. This just moves to the next CPU when stop is called (e.g. nothing was added once the print_tickdevice was printed). Do you think this could be correct? diff --git a/kernel/time/timer_list.c b/kernel/time/timer_list.c index 3bdf283..8d36a3d 100644 --- a/kernel/time/timer_list.c +++ b/kernel/time/timer_list.c @@ -327,8 +327,10 @@ static void *timer_list_next(struct seq_file *file, void *v, loff_t *offset) return timer_list_start(file, offset); } -static void timer_list_stop(struct seq_file *seq, void *v) +static void timer_list_stop(struct seq_file *file, void *v) { + struct timer_list_iter *iter = file->private; + iter->cpu = cpumask_next(iter->cpu, cpu_online_mask); } static const struct seq_operations timer_list_sops = { -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
