I'm not sure I understand the question. We already do a number of capable type security checks in dummy functions. See dummy_settime() as just one example. If we have !CONFIG_SECURITY we don't have any security protections (how could we? we turned them off) so we don't get into dummy hooks. If we do checks or not in uncompiled code doesn't seem to me to matter. Maybe I'm just confused... -Eric - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
