In a nutshell...

Vnodes are very similar to the System V file system switch.  They provide
a layering between the generic file system activities and the file system
specific activities so that you will not have to change any code in the
generic layer when you want to add a new file system type.  

This is a part of the system that you will never have to deal with unless
you are adding support for new file systems to the kernel.
