The patch adds NFS support for SELinux xattrs.
No, it makes NFS lie about setting the SELinux attribute, while not
truly setting it at all (other than in-core). So it is then lost when
the inode is evicted from memory or the system reboots. The patch was
rejected upstream. The problem lies in cp (coreutils), not NFS, IIUC -
it is making faulty assumptions about setxattr() always being supported
when getxattr() is.
