   My suggestion is indeed effectivly (almost) doubling the inode size.

   However, it provides an upgrade path, where you can double-boot with a
   kernel that DOESN"T know about the inodes.

The 2.2 kernels already compute EXT2_INODE_SIZE based on a value in the
superblock. So an old kernel will be able to deal correctly if we
double the size of the inodes.

Credit me with at least *some* foresight. :-)
