Virtual File Systems(虚拟文件系统) Virtual File Systems(VFS,虚拟文件系统)provide an object-oriented way of implementing file systems. VFS allows the same system call interface(the APl)to be used for different types of file systems. The APl is to the VFS interface,rather than any specific type of file system. file-system interface VFS interface local file system local file system remote file system type 1 type 2 type 1 dis network Schematic View of Virtual File System 口”4814在4生，主月QC. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
