If nobody else is already working on these cleanups in ext2 following your 
suggestion, I'd be happy to work on this by the end of this week. I only need 
a confirmation because I'd hate to duplicate someone else work.

I don't know this other filesystem but I could take a look and see whether it 
resembles somehow sysv and ext2 (if so, this work would be pretty simple too, 
thanks to your kind suggestions when I worked on sysv and ufs).

I'm adding Jan to the Cc list to hear whether he is aware of anybody else 
working on this changes for ext2. I'm waiting for a reply from you (@Al) or 
Jan to avoid duplication (as said above).

Thanks,

Fabio
