I would note that one of our developers has noticed it 3 year ago.
it was w/o comments too.

I did not found any arguments explaining Ted's reasons, I believe he did not
noticed that he had inversed this condition. If otherwise he had some important
reasons, there is another bug: he must change the documentation at least.
I would like to add that our customers are really discontented by this change.
Now they pays a high price for any minor ext3 errors: they should stop any
processes that uses this partition, check the partition, restart the processes
again... Downtime is too long and there is not any workarounds.

On the other hand if error is not saved on the disc, fsck will not check this
filesystem automatically on the next reboot and therefore node will mount
corrupted filesystem, it's dangerous too. In the worst scenario the node find
the same error on the disc and rebooted again and it is real nightmare for
I would note that Eric Lammerts has tried to fix this issue, however I'm not
sure that he has achieved a success:
Also I would like to add that Andrew Morton has signed off the patch and added
