Async Crypto API

[Dmitry Kasatkin <dmitry.kasatkin@nokia.com>]

Hello,

I have one question about async api.

I work on AHASH driver and wonder about one thing.

while calculating hash, client might call many times

ahash_request_set_crypt(req, &sg, sha1, len);
crypto_ahash_update(req);
..
..
ahash_request_set_crypt(req, &sg, sha1, len);
crypto_ahash_finup(req);

right?

But because it is async and driver does not wait_for_completion,
 previous request may not be completed before client will call next update.

But what should be the behavior of the driver?

Thanks,
Dmitry
