crypto: hash - Count error stats differently Move all stat code specific to hash into the hash code. While we're at it, change the stats so that bytes and counts are always incremented even in case of error. This allows the reference counting to be removed as we can now increment the counters prior to the operation. After the operation we simply increase the error count if necessary. This is safe as errors can only occur synchronously (or rather, the existing code already ignored asynchronous errors which are only visible to the callback function).

crypto: hash - move "ahash wrapping shash" functions to ahash.c The functions that are involved in implementing the ahash API on top of an shash algorithm belong better in ahash.c, not in shash.c where they currently are. Move them. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: hash - Add crypto_clone_ahash/shash This patch adds the helpers crypto_clone_ahash and crypto_clone_shash. They are the hash-specific counterparts of crypto_clone_tfm. This allows code paths that cannot otherwise allocate a hash tfm object to do so. Once a new tfm has been obtained its key could then be changed without impacting other users. Note that only algorithms that implement clone_tfm can be cloned. However, all keyless hashes can be cloned by simply reusing the tfm object.
