Subject: About multiple queries to control using $DBGMT/dynamic_debug/control

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!
