From ec8e6a4e062e2edebef91e930c20572c9f4c0dda Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Thu, 11 Feb 2010 09:43:20 +0900 Subject: TOMOYO: Add refcounter on domain structure. Add refcounter to "struct tomoyo_domain_info" since garbage collector needs to determine whether this struct is referred by "struct cred"->security or not.
