From 72cb6962a91f2af9eef69a06198e1949c10259ae Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 20 Jun 2005 13:18:08 -0700 Subject: [IPSEC]: Add xfrm_init_state This patch adds xfrm_init_state which is simply a wrapper that calls xfrm_get_type and subsequently x->type->init_state. It also gets rid of the unused args argument. Abstracting it out allows us to add common initialisation code, e.g., to set family-specific flags. The add_time setting in xfrm_user.c was deleted because it's already set by xfrm_state_alloc. Signed-off-by: Herbert Xu Acked-by: James Morris Signed-off-by: David S.
