Summary: Linux Kernel uses a lot of Data Structure Knowledge. Although Linux is written in C language, many of the content in it is an object-oriented idea. Therefore, the knowledge of data structures is very basic and important. Data structure

Loop linked list, the final tail pointer pointing to the head knot point, two-way loop linked list is to add a pre pointer. Questions about Joseph's ring: set N people numbered 1, 2, 3,... n to sit in a circle. The person whose sequence number is K (

Shortcuts to learning: write more code STACK: A stack is a linear table that restricts the insert and delete operations on one end. The row number is also a linear table. That is to say, there are two storage methods: sequential stack and chained

In previous articles, we used ia32 and x86_64. There was a problem with the machines that installed IA64 on the network. The most important thing was that pxelinux did not support IA64 and replaced it with elilo, which was made by HP. The most
