From: James Morris <jmorris@redhat.com>
This patch modifies the kernel's NFS mount data structure to include SELinux
context mount data. It allows NFS fileystems to be labeled on a
per-mountpoint basis, and should not affect existing versions of userspace
mount.
(A patch to the userspace mount code is available at
http://people.redhat.com/jmorris/selinux/context_mounts/)
