From 2d0f230fe0649758394466cb69b553c0e8184df9 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 21 May 2015 15:11:02 +0800 Subject: [PATCH] crypto: aead - Rename aead_alg to old_aead_alg This patch is the first step in the introduction of a new AEAD alg type. Unlike normal conversions this patch only renames the existing aead_alg structure because there are external references to it. Those references will be removed after this patch.
