Hi Ted,

Could please take a look at this patch series?  It has been sent out
for a long time.  I have forgotten it completely until I clean up my
e2fsprogs tree.  I try to rebase this patch series against the latest
master branch of e2fsprogs tree, and it can be applied without any
changes.

Thanks,
                                                - Zheng
