This change to build upon dumb buffers was suggested by me, as dumb 
buffers is the closes thing there is to a buffer management interface. 
Drivers with 'smart buffers' would have to add their own ioctl interfaces.

What I really miss here is a userspace application that uses this 
functionality. It would be much easier to discuss if there was an actual 
example.
