Aha. I missed that the seed is injected into buf before passing it

before the first iteration of the loop (or, in my case, since I was
testing with a 6 char filename, the only iteration).

I will repeat my experiment with that and see if I can tease it out.

BTW, if you are looking for a userspace implementation of the hash,
it's available in libext2fs in e2fsprogs.
