If you have a fieldbus device you want to add to mainline Linux, and
you wish to piggy-back onto the fieldbus_dev subsystem, then we can
discuss fieldbus API changes/additions/improvements during the
patch review stage.

It's my experience that good userspace APIs evolve from practical
requirements, not top-down theoretical design. The staging/ location
allows us to take an evolutionary approach.
