[summary] ufsdump can not do the math?

From: Michael Wang (mwang@tech.cicg.ml.com)

The patch 105722-03 fixed the problem. The README for the patch did not
mention the problem, so I think the problem is accidently fixed while
they fix other bugs, or the developers forget to mention it.

Some people told me it is a known bug (bugIDs: 1250684, 4017060, 4166125)
and they have not found a fix. So I hope this summary can be of help.

Thanks.
