From 78a1fe4f242cbe6b4578e072b75e171b92745afa Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 24 Dec 2006 10:02:00 +1100 Subject: [PATCH] [CRYPTO] api: Use structs for cipher/compression Now that all cipher/compression users have switched over to the new allocation scheme, we can get rid of the compatility defines and use proper structs for them.
