Please, remember the original goal. It is new wear-levelling. This patch
may be considered as something independent, but it is not optimal. If we
follow this way, Zhao must:

1. Write code which understands both cleanmarkers and EB headers.
2. Test that old images are actually work well on new JFFS2.
3. Implement 1:1. Remove cleanmarkers support as they are not needed
anymore.

So, there is unneeded work. Does it make sense to regard these problems
coincidentally?
