From 1cac2cbc76b9f3fce0d4ccc374e724e7f2533a47 Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Sun, 18 Jan 2009 16:19:46 +1100 Subject: crypto: cryptd - Add support to access underlying blkcipher cryptd_alloc_ablkcipher() will allocate a cryptd-ed ablkcipher for specified algorithm name. The new allocated one is guaranteed to be cryptd-ed ablkcipher, so the blkcipher underlying can be gotten via cryptd_ablkcipher_child().
