If you've ever written anything kernel side for Linux, I'm sure you've bashed your head on the keyboard as many times as I have looking through lackluster documentation and scouring source files to find structure definitions. Here's a little script that will show you the source file and line number of the given structure definition.
First of all, this script relies on a fantastic website that allows you to easily search through the Linux source files http://lxr.linux.no. I simply wrote a script to parse the output to show structure definition locations. Change the URL in the script depending on your current kernel version number.
