This would need to change several places in UBI and UBIFS and switch
from continuous vmalloc buffers to iterating over an array of smaller
buffers.

I was thinking about this in the past but this is rather big project (a
months or a couple I'd say) so I did not have time to do this.

I think we basically need to switch to flexible arrays
(Documentation/flexible-arrays.txt), but last time I looked at this I
remember I decided that flexible arrays functionality would need to be
extended for our purposes.

If someone seriously is going to do this work, I am happy to discuss.
