i know c language.my goal read linux kernel.so languages should learn(write books too) before start reading kernel , there book reading linux kernel this book little outdated, understanding linux kernel amazing reference. give crash course in i386 features make lot of kernel facilities possible (such mmu , how interrupts work. operating systems, it's hard understand hardware ends , os begins), , reference lot of critical source directly. also, lwn kernel article index more up-to-date references. one way start come simple feature you'd add kernel , start hacking away @ it.
