With FCB, it's possible to manage both file cache and memory mapping.
To my understanding, "双FCB" means there are two FCBs created for the same file stream on disk. One FCB is used to maintain cipher text, the other one is used to maintain plain text. What I believe is that one FCB can only maintain one cache. Without "双FCB", I don't think "双缓冲" is possible. |

似乎有些文件系统本身就会用到两个FsContext

Are you talking about FsContext and FsContext2? FsContext2 is not FCB, it's CCB.
