Well, to be clear I didn't just double the size of the inode table. It
is dynamically
determined based on the data structure. I'm not a file system expert (to call me
a novice would probably be stretching it), so I'm hoping someone more versed
can chime in.

All the code does is query the data structure (specifically, the s_inode_size
field of the structure) and use that value instead of blindly assuming an inode
size of 128. I don't think it's a matter of what is done with the
extra bits, since
it's just querying the size of an already created filesystem.

Thanks,
Josh
