well, let's see... I think we read "inode_size" in get_next_inode_full,
which is s_inode_size, into buf, which was allocated to size
inode_size/s_inode_size.

But "inode" is just a plain ol' little inode.  I think really this
"inode" is just for convenience for accessing the normal inode fields....

But I now that I try livecd-creator with this patch, even on 128-byte
inodes, the fscks it runs is finding trouble post-resize (this despite
all the regression test passing...)  *sigh* I think I'd better sit on
this problem for a while longer before I send the next patch :)

Ted, pls ignore this for now...
