From 1581e7ddbdd97443a134e1a0cc9d81256baf77a4 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Sat, 21 Feb 2009 20:40:50 +0900 Subject: TOMOYO: Do not call tomoyo_realpath_init unless registered. tomoyo_realpath_init() is unconditionally called by security_initcall(). But nobody will use realpath related functions if TOMOYO is not registered. So, let tomoyo_init() call tomoyo_realpath_init(). This patch saves 4KB of memory allocation if TOMOYO is not registered.
