Yeah, I wasn't all that comfortable even with trying to hash it
(because I think the number of source bits is small enough that even
with a crypto hash, it's trivially brute-forceable).

See

   https://lore.kernel.org/all/20240122152748.46897388@gandalf.local.home/

for the current patch under discussion (and it contains a link _to_
said discussion).
