Yes, these will be good to have and is listed as todo. > So with a little > modification of parse_probe_arg(), uprobe_event can support @ADDR, > $retval, offs(FETCHARGS) except @SYM, $stack, $stackN. Is it right? For some of these like the @sym, trace_uprobe.c may not be the right place because the kernel will not be able to decode user space symbols. $retval needs uretprobes support -- Thanks and Regards Srikar -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
