Please print a more useful message like "inode size must be a power of two",
as "bad inode size - 200" isn't very useful to the user to figure out what
a good inode size is.

This isn't doing swabbing of the inodes?

This isn't doing swabbing either?

Shouldn't this be verified when the inode size is parsed instead of down here?

Why do you capitalize "Inode" in all of the messages?
