Does this code compile? The struct bpf_crypto_type definition in
include/linux/bpf_crypto.h doesn't have .hash or .digestsize fields at
this commit. The commit message says "Update the bpf_crypto_type
interface with hash-specific callbacks" but the interface wasn't
actually updated in this commit.

Looking forward in the git history, commit 51e5f5be27dc adds these
fields to the interface. Should that commit come before this one for
bisectability?
