Hmm, you mean that I'll lost the backward compatibility in case of 
unclean reboot. Yes, you are right. Thanks.

But... from the another hand, this is only in case of unclean reboots... 
Moreover, we may do this only for _big files_ ...

What would you say if somebody offer you a patch with such optimization 
? Would you reject it? Or you would accept it and rename JFFS2 to JFFS3 
:-) ?

Hmm, yes. I meant JFFS2 as whole, with all its optimizations.

Anyway, the complex solution with partial fragtrees is the potential 
source of new bugs, etc.
