内存映射文件是不是通过FastI/O实现的？
如题。两者都不经过filesystem直接读缓冲数据。它们是什么关系？

MM file is not using Fast I/Os. MM is backed by VMM directly while Fast I/Os access data through CM which needs VMM to handle page fault. Both MM file and Fast I/Os are tightly coupled with file system. MM and Fast I/Os are two big topics hardly explained in just a few sentences. Suggest reading the book "NT File System Internals".
