Summary
This chapter is one of the most important chapters. It demystifies memory management and allocation (how and where) in the kernel. Every memory aspect is discussed and detailed, and devres is also explained. The caching mechanism is briefly discussed in order to give an overview of what goes on under the hood during I/O operations. It is a strong base from which to introduce and understand the next chapter, which deals with DMA.
