From 8ae8f1627f39bae505b90cade50cd8a911b8bda6 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Mon, 3 Jun 2013 19:46:19 +0900 Subject: f2fs: support xattr security labels This patch adds the support of security labels for f2fs, which will be used by Linus Security Models (LSMs). Quote from http://en.wikipedia.org/wiki/Linux_Security_Modules: "Linux Security Modules (LSM) is a framework that allows the Linux kernel to support a variety of computer security models while avoiding favoritism toward any single security implementation. The framework is licensed under the terms of the GNU General Public License and is standard part of the Linux kernel since Linux 2.6. AppArmor, SELinux, Smack and TOMOYO Linux are the currently accepted modules in the official kernel.".
