Making Simple Modifications to the Linux Source

Computer Code

March 23, 2018

This post is Part 2 of a series on the Linux kernel. Part 1 - Part 3 The Linux kernel is one of the most complex open-source projects available to the public, and the source code that comprises it is highly intricate, to say the least. Knowing this, I wondered what it would take to pick apart such a technological beast and actually begin to understand it. The key to understanding, like anything else, is to learn by doing.

You may hate the line at the DMV, but without it, things might turn into a rough-and-tumble free for all! In the same way that a line keeps raging motorists from getting out of hand, a Queue helps your computer keep its ducks in a row. The Queue functions very much like a line of people. It’s a First-In, First-Out (FIFO) data structure, so no cutting! Starting Out Bear with me.

Need a quick run down on a classic data structure? Look no further. Click here for the full LinkedList source code. Also, here is the test code. A linked list is an ordered collection of elements. The thing that makes it special is how it stores data. Behind the scenes, each number, string, object, or other value you may need to keep track of is stored in a Node. Each Node references its successor.
