|  | Filesystems in the Linux kernel | 
|  | =============================== | 
|  |  | 
|  | This under-development manual will, some glorious day, provide | 
|  | comprehensive information on how the Linux virtual filesystem (VFS) layer | 
|  | works, along with the filesystems that sit below it.  For now, what we have | 
|  | can be found below. | 
|  |  | 
|  | Core VFS documentation | 
|  | ====================== | 
|  |  | 
|  | See these manuals for documentation about the VFS layer itself and how its | 
|  | algorithms work. |
