49 * and so that they can be shared.
50 *
51 * Labels are never modified in place. Anytime a label
52 * is imported (e.g. xattrset on a file) the list is checked
53 * for it and it is added if it doesn't exist. The address
54 * is passed out in either case. Entries are added, but
55 * never deleted.
56 *
57 * Since labels are hanging around anyway it doesn't
58 * hurt to maintain a secid for those awkward situations
59 * where kernel components that ought to use LSM independent
60 * interfaces don't. The secid should go away when all of
61 * these components have been repaired.
