From 21380b81ef8699179b535e197a95b891a7badac7 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 22 Feb 2006 14:47:13 -0800 Subject: [XFRM]: Eliminate refcounting confusion by creating __xfrm_state_put(). We often just do an atomic_dec(&x->refcnt) on an xfrm_state object because we know there is more than 1 reference remaining and thus we can elide the heavier xfrm_state_put() call. Do this behind an inline function called __xfrm_state_put() so that is more obvious and also to allow us to more cleanly add refcount debugging later.
