From d6ef2f198d4c9d95b77ee4918b97fc8a53c8a7b7 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 11 May 2015 17:47:39 +0800 Subject: crypto: api - Add crypto_grab_spawn primitive This patch adds a new primitive crypto_grab_spawn which is meant to replace crypto_init_spawn and crypto_init_spawn2. Under the new scheme the user no longer has to worry about reference counting the alg object before it is subsumed by the spawn. It is pretty much an exact copy of crypto_grab_aead. Prior to calling this function spawn->frontend and spawn->inst must have been set.
