From 2e71029e2c32ecd59a2e8f351517bfbbad42ac11 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Tue, 22 Apr 2014 21:48:30 +0900 Subject: xfrm: Remove useless xfrm_audit struct. Commit f1370cc4 "xfrm: Remove useless secid field from xfrm_audit." changed "struct xfrm_audit" to have either { audit_get_loginuid(current) / audit_get_sessionid(current) } or { INVALID_UID / -1 } pair. This means that we can represent "struct xfrm_audit" as "bool". This patch replaces "struct xfrm_audit" argument with "bool".
