That also being said... does a 32-bit sector_t make any sense on a

depend on 64-bit sector_t and be done with it.
Is this really necessary? There are a few features, which would make ext4 also interesting at the low end (e.g. extents). Storing 64bit values on disk is fine, but they should be converted to native values as soon as possible.
