From ebc610e5bc76df073221e64e86c3f7533a09ea40 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 1 Jan 2007 18:37:02 +1100 Subject: [CRYPTO] templates: Pass type/mask when creating instances This patch passes the type/mask along when constructing instances of templates. This is in preparation for templates that may support multiple types of instances depending on what is requested. For example, the planned software async crypto driver will use this construct. For the moment this allows us to check whether the instance constructed is of the correct type and avoid returning success if the type does not match.
