This solution has been in my patch.

Until now we only disscussed one aspect of the problem.
Another aspect is that what should we do when users mount new JFFS2 image
with old JFFS2 code? Is the "big warning" in readme enough? Or we should
let old JFFS2 code reject mounting new JFFS2 image?

Thanks,
