If you feel that hardcoding u64 as sector numbers will mean ext4 suddenly
fails on 32-bit, you misunderstand the situation completely.
With CONFIG_LBD disabled you still had the truncation/complexity issues
somewhere else, so you gain nothing, but waste memory in ext4.
You gain simplicity and reduced number of code paths.
"waste memory" is hardly a significant argument. I doubt you will
notice a difference.
