-functions. If you don't need it, remove it.

put_super: called when the VFS wishes to free the superblock
(i.e. unmount). This is called with the superblock lock held
- write_super: called when the VFS superblock needs to be written to
- disc. This method is optional
-
sync_fs: called when VFS is writing out all dirty data associated with
a superblock. The second parameter indicates whether the method
should wait until the write out has been completed. Optional.
