Where can I get Ubuntu's source code? Actually I want It's kernel's code. I know I can get the kernel from kernel.org but as I found out that Ubuntu does some patching on the kernel I want to know what are those patches. And yes I know Ubuntu's kernel code can be found in an installed Ubuntu in the file system but thats just the code! I want specifically those patches separately and if any some comments or documents about them. Where can I get these things?
