765 * The permissions for the special ACL entries (u::, g::[m::], o::) are
766 * actually stored in the file mode (if there is both a group and a mask,
767 * the group is stored in the ACL entry and the mask is stored on the file).
768 * This allows the mode to remain automatically in sync with the ACL without
769 * the need for a call-back to the ACL system at every point where the mode
770 * could change. This function takes the permissions from the specified mode
771 * and places it in the supplied ACL.
772 *
773 * This implementation draws its validity from the fact that, when the ACL
774 * was assigned, the mode was copied from the ACL.
775 * If the mode did not change, therefore, the mode remains exactly what was
776 * taken from the special ACL entries at assignment.
777 * If a subsequent chmod() was done, the POSIX spec says that the change in
778 * mode must cause an update to the ACL seen at user level and used for
779 * access checks. Before and after a mode change, therefore, the file mode
780 * most accurately reflects what the special ACL entries should permit/deny.
781 *
782 * CAVEAT: If someone sets the SGI_ACL_FILE attribute directly,
783 * the existing mode bits will override whatever is in the
784 * ACL. Similarly, if there is a pre-existing ACL that was
785 * never in sync with its mode (owing to a bug in 6.5 and
786 * before), it will now magically (or mystically) be
787 * synchronized. This could cause slight astonishment, but
788 * it is better than inconsistent permissions.
789 *
790 * The supplied ACL is a template that may contain any combination
791 * of special entries. These are treated as place holders when we fill
792 * out the ACL. This routine does not add or remove special entries, it
793 * simply unites each special entry with its associated set of permissions.
