Well, why is it better?  Is it easier to rebase my patch onto yours?
My patch fixes a critical problem that epoch information will be
corrupted after session timeout.  Currently, there is no way to fix
the broken epoch other than re-formatting the cluster.

If you could review my patch and add your Reviewed-by tag, I would
apply this patch asap.  Yuan is offline this week, so reviews from
other developers are highly appreciated.  But if there is a reason
your patch should be applied first, I'll wait for your patch. :)

Thanks,
