Then why not massage the ring into what you need from a ring buffer?  Come up 
with some real design criteria that are to be satisfied so some real 
direction can be had in discussions.

Want a patch that spews "->read() is not async" for every device in the 
kernel?  That would get attention.  As it stands today, nobody cares for 
functionality that they aren't directly involved with and which does not 
block development.  Patches have been bounced around doing aio via threads 
but almost always got dropped for some reason or other, I just don't have 
the time to carry them around indefinately.
