From 32528d0fbda1093eeeaa7d0a2c498bbb5154099d Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 10 Sep 2007 15:51:11 +0800 Subject: [PATCH] [CRYPTO] blkcipher: Fix inverted test in blkcipher_get_spot The previous patch had the conditional inverted. This patch fixes it so that we return the original position if it does not straddle a page. Thanks to Bob Gilligan for spotting this.
