This is because the approach-1 doesn't show the latest value of
sync_status. I mean in the latest cycle if the sync is successful, it
won't update the stats which I am not sure is correct because users
may want to know the recent status of sync cycle. Otherwise, the patch
should be almost the same. I think we can even try to write a patch
for approach-2 without an additional out parameter in some of the
functions.
