From 5448ec4f5062ef75ce74f8d7784d4cea9c46ad00 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Mon, 21 Jun 2010 11:14:39 +0900 Subject: [PATCH] TOMOYO: Use common code for domain transition control. Use common code for "initialize_domain"/"no_initialize_domain"/"keep_domain"/ "no_keep_domain" keywords.
