From e45009229be6a7fae49bdfa3459905668c0b0fb1 Mon Sep 17 00:00:00 2001 From: David S. Miller Date: Wed, 19 May 2010 14:12:03 +1000 Subject: crypto: testmgr - Add testing for async hashing and update/final Extend testmgr such that it tests async hash algorithms, and that for both sync and async hashes it tests both ->digest() and ->update()/->final() sequences.
