Thanks for working on this. Some comments:

Is it really part of glibc? If not, please remove that comment.

Did you try different buffer sizes?
In coreutils, we have a little script to determine the optimal BLOCKSIZE
- which is 128*1024 since 2014:

Linux supports accessing kernel crypto API via AF_ALG since
version 2.6.38. Coreutils uses libcrypto when available and fallbacks to
generic C implementation of various hashing functions.
Add a generic afalg_stream() function which uses AF_ALG to calculate the
hash of a stream and use sendfile() w
Let md5sum and all sha*sum utilities use Linux kernel cryptographic API via the
AF_ALG address family.
Speed gain depends on the CPU type:
