From 124b53d020622ffa24e27406f2373d5a3debd0d3 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 16 Apr 2007 20:49:20 +1000 Subject: [CRYPTO] cryptd: Add software async crypto daemon This patch adds the cryptd module which is a template that takes a synchronous software crypto algorithm and converts it to an asynchronous one by executing it in a kernel thread.
