Yes, the 'swap' is nothing to worry about.
As md does it's checks in units of around 128 sectors, the "md0: 128"
probably just means a single sector is different between the two.
I recommend
echo repair > /sys/block/md0/md/sync_action
That will fix it.
Probably just another 'fsck -f' after that just to be on the same
side.
