From 70e94e66aec255aff276397f5ed3f3626c548f1c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?YOSHIFUJI=20Hideaki=20/=20=E5=90=89=E8=97=A4=E8=8B=B1?= =?UTF-8?q?=E6=98=8E?= Date: Tue, 29 Jan 2013 12:48:50 +0000 Subject: xfrm: Convert xfrm_addr_cmp() to boolean xfrm_addr_equal(). All users of xfrm_addr_cmp() use its result as boolean. Introduce xfrm_addr_equal() (which is equal to !xfrm_addr_cmp()) and convert all users.
