Virtual File Systems
- VFS concept tries to integrate multiple file systems into an orderly structure.
- The key idea is to abstract out that part of the file system that is common to all file systems and put that code in a separate layer that calls the underlying concrete file systems to actually manage the data.
POSIX
- To the user processes.
VFS interface
- To the concrete file systems. This interface consists of dozen function calls that the VFS can make to each file system to get work done.
NFS
- Support remote file systems. So it doesn't represent partitions on a local disk.
process table
- file descriptors
- V-nodes
- Function pointers
- V-nodes
