My new patchset intends to expand on your earlier inode/superblock patches by
adding checksums to nearly all metadata objects (directory blocks, htree,
extent tree, block/inode bitmaps, extended attributes).  It also adds code to
e2fsprogs to verify the checksums, and make the necessary adjustments to the
on-disk format to add space for checksums.
