Subject: [PATCH 05/10] KConfig: Add KConfig entries for Labeled NFS

This patch adds two entries into the fs/KConfig file. The first entry
NFS_V4_SECURITY_LABEL enables security label support for the NFSv4 client while
the second entry NFSD_V4_SECURITY_LABEL enables security labeling support on
the server side.
