One possible issue is the return value - I don't have the original patch so I don't know what is the call site, so I don't know if that is an issue. But you don't want to do a dump_stack for no reason. That would at best be very misleading, and I would imagine be quite expensive. julia -- 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/
