Subject: [PATCH 07/10] kernfs: add kernfs_open_file->priv
Date: Mon, 3 Feb 2014 14:09:14 -0500 [thread overview]
Message-ID: <1391454557-32376-8-git-send-email-tj@kernel.org> (raw)
In-Reply-To: <1391454557-32376-1-git-send-email-tj@kernel.org>
Add a private data field to be used by kernfs file operations. This
generally makes sense and will be used by cgroup.
