Subject[PATCH] (2/3) SELinux context mount support - NFS
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/)
