Well actually the intention of this part was mostly to have a proper way of
verifying the checksums we write in the checksum tree.
I have a patchset in development that adds SHA-256 in the mix (it's actually
very similar to the patch you've referenced).
Apart from SHA-256 I want to have a not cryptographically secure checksum as
well which would help detecting duplicate extents and can be used for
de-duplication.
But this patchset is not anywhere near I can (or better want to) show to
someone.
Thanks for your patience.
