Chapter 3: Dealing with Kernel Core Helpers
The Linux kernel is a standalone piece of software—as you'll see in this chapter—that does not depend on any external library as it implements any functionalities it needs to use (from list management to compression algorithms, everything is implemented from scratch). It implements any mechanism you may encounter in modern libraries and even more, such as compression, string functions, and so on. We will walk step by step through the most important aspects of such capabilities.
In this chapter, we will cover the following topics:
- Linux kernel locking mechanisms and shared resources
- Dealing with kernel waiting, sleeping, and delay mechanisms
- Understanding Linux kernel time management
- Implementing work-deferring mechanisms
- Kernel interrupt handling
