Hi Peng, Yes that's the right kernel code. Once you have that you can apply the patch. Even though that files aren't there, they should be created by the patch.
$ git apply patch-file-name Or if the patch doesn't apply properly, you can look at the patch file and apply it manually. Here's the one I compiled which includes the kernel info https://www.dropbox .com/s/wf09b4kkn3jh4ku/vmlinux-with_kernel_info If you use that, it should get you past the "thread info not compiled into kernel" problem. Then you should be able to get the PID using the code snippet that I pointed to in my previous message. Let me know if that doesn't work.
