Fortunately, th

1. The high-speed buffer zone is located between VFS and a specific file system. 2. The file node on the disk contains the strcut address_space field. The structure corresponds to the file node on the disk. 3. A struct address_space contains one or more cache pages. The cache pages are organized by the base tree for easy search. 4. Each cache page contains
