And - again - NACK. Calling a subsystem just iec61158 is going to hide
what it is and stand in the way of development of this niche system. I
asked Enrico to come up with a better naming proposal such as having
iec61158 as subfolder to human-readable fieldbus, but I did not see him
coming up with any such new proposals apart from repeating this name.

Also please read Sven's comment again: It you don't like the current
naming you'll need to post follow-up patches, as v11 of this subsystem
has been merged into staging. No complaint about piggy-backing on v10 is
going to change that fact now!

And since we're at it, Enrico's response to me just threw around a bunch
of acronyms instead of explaining which ones have an _actual_ conflict
with this subsystem - my point precisely was that if they use sockets or
ttys then there's no real conflict apart from lots of things classifying
as "fieldbus".

Regards,
Andreas
