How many users really need to know this? Some users are confused by static metadata blocks allocated by extN file systems. Blocks used as inode tables and bitmaps can be calculated by data from dumpe2fs. However, blocks taken up by super blocks and GDT can not be calculated. So this patch prints the number of blocks used by super blocks and GDT. IMHO, it is useful for some users who know little about extN. I met several users who ask why a fresh ext4 has used so many blocks compared to others. I know most of them are used as inode tables. Without this patch, we can explain the problem. I just think we can explain the problem with explicit numbers with the patch.
