How does one mount an existing jffs2 partition so it is writeable?

I'm beginning to wonder if we should make JFFS2 unlock automatically if it 
finds at least some JFFS2 nodes. Or put in the 'is_flash_locked' method and 
make JFFS2 notice that it's locked _before_ trying to write to it, and 
print an appropriate message and mount in read-only mode so it doesn't even 
let you _try_ to write to it.
