That's what I've been discussing with Jens elsewhere on this list.
However, I think what you're proposing is overly complex.  All we really
need is for a way of flagging a kobject (or kref) so the final put will
be in user context.  Then we can use storage within the kobject or
device (or something else) for the purpose.
