My initial thought was that you were right (and I did just copy the
CTA_HELP implementation), but now I've decided that I like that nest.  I
have no idea what future representation an LSM might use.  The only 2
LSMs that make sense to use this interface SELinux and SMACK both use a
string, but I don't know why we have to limit it to that....
