Hi,
Didn't took the time  to read the code, I'll try to do so soon.
Could you tell us more about what you did and how it works ?
Is it similar to yaffs checkpoints ? When are the log written ?
What will happen if you try to mount something that used UBIL with a
kernel without UBIL support ?
Thanks,
