What UNIX called an inode is unfortunately not what Linux now calls an inode. That thing might have better names, but we are stuck with it.

and here's an ext4 on-disk inode: http://lxr.free-electrons.com/source/fs/ext4/ext4.h#L704
The latter is considerably larger, to be sure, but still contains all of the fields from the former (many of them with the same name!).
