From: Rabin Vincent Subject: [PATCH] crypto: doc - Fix hash export state information Date: Wed, 25 Jan 2017 16:55:06 +0100 Message-ID: <1485359706-7184-1-git-send-email-rabin.vincent@axis.com> Cc: linux-crypto@vger.kernel.org, smueller@chronox.de, Rabin Vincent To: herbert@gondor.apana.org.au Return-path: Received: from bastet.se.axis.com ([195.60.68.11]:41293 "EHLO bastet.se.axis.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751429AbdAYPzK (ORCPT ); Wed, 25 Jan 2017 10:55:10 -0500 Sender: linux-crypto-owner@vger.kernel.org List-ID: From: Rabin Vincent The documentation states that crypto_ahash_reqsize() provides the size of the state structure used by crypto_ahash_export(). But it's actually crypto_ahash_statesize() which provides this size.
