VFS and FS i-node difference
- by gaffcz
What is the difference between VFS i-node and FS (e.g. EXT) i-node?
Is it possible that EXT i-node is persistent (contains/points to data blocks), but VFS i-node is created just in i-node cache after read/use of EXT i-node?
Or the VFS i-node is just an image of FS i-node (it's the same) and i-nodes in those systems, which are not working with i-nodes (e.g. FAT, NTFS) has to be emulated (HOW?) to allow VFS work with those FS like they would support i-nodes?
