Description: Buddy（伙伴）算法每次分配包含一个或者多个物理页面的内存块，页面以2的次幂的内存块来分配。首先搜寻满足请求大小的页面，它从满足当前申请大小的Buddy数据结构的m_ freePages域着手沿链来搜索空闲页面。如果没有这样请求大小的空闲页面，则它搜索两倍于请求大小的内存块。这个过程一直将持续到所有的Buddy 被搜索完或找到满足要求的内存块为。如果找到的页面块大于请求的块则对其进行分割以使其大小与请求块匹配。由于块大小都是2的次幂所以分割过程十分简单：空闲块（低地址）被连进相应大小的队列而这个页面块被分配给调用者。 释放时，先检查该块的伙伴的使用情况，如果没有被使用，则合并这对Buddy，再检查该两倍大小的块的Buddy，一直持续到合并后的块没有Buddy为止，并将之链到该大小的freepage队列中。-Buddy (partners) each allocation algorithm contains a number of physical pages or blocks of memory, two pages to the Powers of the block of memory to allocate. First of all search requests to meet the size of pages, from the application to meet the current size of the data structure Buddy 8 freePages domain proceed along the chain to search leisure pages. If no such request size spare pages, which then search request twice the size of a memory block. This process has to continue until all the Buddy Search End or were found to meet the requirements for the memory block. If found in the pages block greater than the requested block is divided in its size and make it the request block matching.

Description: Buddy(伙伴算法)最让人为之激动的在于它释放回收页面过程中将小内存合并成大内存进而减少碎片的功能,
下面让我们来看看释放页面的函数__free_pages_ok()的具体实现.-Buddy (partner algorithm) was the most exciting is that it will release the process of recovery page at National Cheng Kung University small memory combined to reduce the debris of memory function, following the release of Let s look at the function page __free_pages_ok () concrete realization.

Description: 内存是计算机系统中储存指令代码和各种数据的主要部件，如果内存短缺或者管理不当，将导致整个系统反应迟缓，甚至崩溃。所以，建立稳定、高效的内存管理策略是一个很重要的且必须面对的问题。现代的操作系统中运用位图、链表等多种手段和算法来管理内存。伙伴算法(Buddy System)是一种经典的内存管理算法。在Unix和Linux操作系统中都有用到。其作用是减少存储空间中的空洞，减少碎片，增加利用率。
本程序模拟了内存管理的过程-Memory is stored in a computer system code and instructions of the main components of data, if the memory shortage or mismanagement will lead to the whole system slow to respond, or even collapse. Therefore, to establish a stable and efficient memory management strategy is a very important and must face. Modern operating systems use digital maps, list and algorithm means to manage memory. Partners algorithm (Buddy System) is a classic algorithm for memory management. In Unix and Linux operating systems are used. Its role is to reduce the storage space in the hollow, to reduce the debris, increasing the utilization rate. This procedure simulated the process of memory management

Description: 实现一个内存分配模拟系统，分配的原则参见“伙伴系统”。
要点：使用链表保存各块内存信息，同一个链表中保存的各块大小相同。
链表中的每个结点形式如下：
从键盘输入欲分配的块的大小，系统给出分配结果，并在屏幕上显示出来（图示方式或文本方式）。
-A memory allocation simulation system, the principle of allocation see the " buddy system" . Points: the use of linked lists to save each block of memory, the same block size saved with a linked list. Each node in the list, in the following form: For the size of the allocated block input from the keyboard, the system gives the distribution results, and displayed on the screen (icon or text).
