Slab内存分配策略与移植

slab内存管理算法具有分配和释放内存速度迅速、内外部碎片非常小等优点。介绍了Linux下该算法实现时采用的主要数据结构及相互间的组织关系,阐明了其管理内存的实现机制。讨论了该算法的可移植性问题,其中主要讲述了一个简便并且高效的分页系统的设计,以及信号量移植的相关问题。

Strategy and Transplantation of Slab Memory Allotment

Slab memory management algorism has such advantages as low time consumption in allocating and freeing memory,little internal and external memory fragments.The implementation of this algorism in Linux is presented at first,including its substantial data structures and those relationships.Transplantation of this strategy is discussed in the following,containing an effective paging design and issues in semaphores.
