I have been learning Linux by myself for about one week. For the very beginning, like my classmates and those who are totally fresh men in Linux, I spent up to two to three days with setting my Gentoo up. And my wireless net still fails to work at this moment and only command-line console is available. But this is not the point I write this article, the purpose is to talk about some intuitions on a further study of the Kernel’s Red-Black Tree. Later I will compose another issue to cover my tough way walking through with setting up my Gentoo and today is for the RBTree.
