[学生焦亮]

 hi, recently I am studying click to research BGP protocal, my computer have been installed two OS, window7 and ubuntu 10.10, To install click kernel module, I have to make a patch to my kernel of ubuntu, and then recompile and install kernel, but I did't find the corresponding patch version in CLICKDIR/etc/VERSION. I have tried all patching version supplied by click 2.0, but I can't finish patching process.
