credential: mac_associate_nfsd_label() This entry point can be utilized by various Mandatory Access Control policies so they can properly initialize the label of files which get created as a result of an NFS operation. This work will be useful for fixing kernel panics associated with accessing un-initialized or invalid vnode labels. The implementation of these entry points will come shortly.
