Change 89430 by csjp at csjp_xor on 2006/01/09 19:53:39

	Add another MAC entry point: mac_associate_nfsd_label. This entry
	point will be utilized by the NFS code to create proper subject
	labels for the NFS related operations. For example, NFS operations
	which result in a file being created will cause files to be
	created with proper labels, if this entry point is defined by the
	security policy.
