Buffer Cache VS. Page Cache

The term, Buffer Cache, is often used for the Page Cache. Linux kernels up to version 2.2 had both a Page Cache as well as a Buffer Cache. As of the 2.4 kernel, these two caches have been combined. Today, there is only one cache, the Page Cache.

也即是说目前只剩下了 Page Cache 。
