From c7fc05992afcf1d63d6d5fb6142c8d39094dbca9 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 24 May 2006 13:02:26 +1000 Subject: [CRYPTO] api: Added cra_init/cra_exit This patch adds the hooks cra_init/cra_exit which are called during a tfm's construction and destruction respectively. This will be used by the instances to allocate child tfm's. For now this lets us get rid of the coa_init/coa_exit functions which are used for exactly that purpose (unlike the dia_init function which is called for each transaction). In fact the coa_exit path is currently buggy as it may get called twice when an error is encountered during initialisation.
