Abstract—The 2.6 Linux kernel employs a number of techniques to improve the use of large amounts of memory, making Linux more enterprise-ready than ever before. This article outlines a few of the more important changes, including reverse mapping, how reverse mapping is used for page reclaim, the use of larger memory pages, storage of page-table entries in high memory, kernel shared memory increases efficiency and flexibility and greater stability of the memory manager.
Index Terms—page-table entries (PTEs), page-direct approach, page reclaiming, reverse mapping (RMAP), translation look aside buffer (TLB), Copy on Write (CoW).
