From 70dec235d8ac8cfb56ed2a3597e7d6c5b801f018 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 1 Sep 2007 16:52:13 +0800 Subject: [CRYPTO] api: Kill crypto_km_types When scatterwalk is built as a module digest.c was broken because it requires the crypto_km_types structure which is in scatterwalk. This patch removes the crypto_km_types structure by encoding the logic into crypto_kmap_type directly. In fact, this even saves a few bytes of code (not to mention the data structure itself) on i386 which is about the only place where it's needed.
