Hi,
	I used the $DBGMT/dynamic_debug/control to control printing debuginfo.But When i wote multiple queries which has at least one didn't match,
the result is ok which no error can return.
	So i think i wrote correct queries.But until using dmesg, i only found error.
	And if parm verbose of dynamic_debug is zero, i can't find the result by dmesg.
	So i think it's not convenient.
	If it did not found any query,it should return error.

Thanks!ÿôèº{.nÇ+‰·Ÿ®‰­†+%ŠËÿ±éݶ\x17¥Šwÿº{.nÇ+‰·¥Š{±þG«éÿŠ{ayº\x1dʇڙë,j\a­¢f£¢·hšïêÿ‘êçz_è®\x03(­éšŽŠÝ¢j"ú\x1a¶^[m§ÿÿ¾\a«þG«éÿ¢¸?™¨è­Ú&£ø§~á¶iO•æ¬z·švØ^\x14\x04\x1a¶^[m§ÿÿÃ\fÿ¶ìÿ¢¸?–I¥

Hi,

You can verify what changes have occured by looking in the
$DBGMT/dynamic_debug/control file, and verifying what statements have
been matched. For example, we add a 'p' when printing is enabled.
Does that address your concern?

As these debug statements come and go, I think I'd prefer not to error
out in this case.

Thanks,
