parentcrypto: shash - introduce crypto_grab_shash() (diff)
crypto: ahash - introduce crypto_grab_ahash()
Currently, ahash spawns are initialized by using ahash_attr_alg() or crypto_find_alg() to look up the ahash algorithm, then calling crypto_init_ahash_spawn(). This is different from how skcipher, aead, and akcipher spawns are initialized (they use crypto_grab_*()), and for no good reason. This difference introduces unnecessary complexity. The crypto_grab_*() functions used to have some problems, like not holding a reference to the algorithm and requiring the caller to initialize spawn->base.inst. But those problems are fixed now. So, let's introduce crypto_grab_ahash() so that we can convert all templates to the same way of initializing their spawns.
