I actually do use incremental hashing later on.   BPF currently
vmallocs() a big temporary buffer just so it can fill it and hash it.
I change it to hash as it goes.

How much data is this supposed to hash on average? If it's a large
amount then perhaps using the existing crypto API would be a better
option than adding this.

This is a good point actually: you didn't explain *why* BPF shouldn't
depend on the crypto API.
