Putting small JFFS images in big devices

Hi,

While attempting to track down a problem I copied a JFFS image from a
8Mibyte device and put it in a 14Mibyte device.  Writing files to the
device results in

Free size accounting screwed
free_chunk_size1 == 0x68208, free_chunk_size2 == 0x0, fmc->free_size ==
0x668208

Looks like something thinks the extra 6Mibyte is free and the somewhere
else thinks it isn't.

Also, can you have MTD devices in RAM? If so how?

David Vrabel.
