Subject: [TOMOYO #6 retry 02/21] Add struct vfsmount to struct task_struct.
Date: Wed, 09 Jan 2008 09:53:22 +0900 [thread overview]
Message-ID: <20080109005418.469053691@nttdata.co.jp> (raw)
In-Reply-To: 20080109005320.323184643@nttdata.co.jp
This patch allows VFS wrapper functions associate "struct vfsmount"
with "struct task_struct" so that LSM hooks can calculate
pathname of given "struct dentry".
