Learning Linux Kernel

Hi I have been working on Linux OS for the last 10 years and it has been very exiting and challenging to learn new technologies based on Linux. I am basically a Sys Admin for Linux with bash programming and configuring and setting up Linux Server including network services like BIND DNS,Apache etc... Although i do not know C and ASM Language, I am very much eager to start learning Linux Kernel Code and contribute to linux kernel codebase sometimes down the line. Please guide/suggest me.
