Hi Richard,

ubifs_dump_meta? Hmmm, but I also dump data nodes in it. Do you have
some reason to rename it? Extend it? Of course, I would like to make it
better and better. But the first step is making it in mtd-utils.

Oh, sorry for sending my patch without any asking. I thought there is
nobody caring about it. And what's more, I am planning to do a fsck.ubifs
actually. Haha, so I think we can cooperate on it. Could you share more
about your work so far?

Thanx a lot. :)

Yea, sounds very interesting, although I am not sure how it can be
implemented. Looking forward your release.

Thanx
