Hi Changbin,

> This patch add wildcard '*'(matches zero or more characters) and '?'
> (matches one character) support when qurying debug flags.
> 
> Now we can open debug messages using keywords. eg:
> 1. open debug logs in all usb drivers
>    echo "file drivers/usb/* +p" > <debugfs>/dynamic_debug/control
> 2.  open debug logs for usb xhci code
>    echo "file *xhci* +p" > <debugfs>/dynamic_debug/control

and this should have a section in Documentation/dynamic-debug-howto.txt.

Regards

Marcel
