Yes it is.  Or at least until you fix all existing users so that if you
do change it, no one notices it happening :)

Then another question is: do we really want to commit to a stable ABI
for a module we only use for testing purposes and which doesn't
interact with any real hardware.

Rewriting this module without any legacy cruft is tempting though. :)

Another thought spoken loudly: maybe it can be unified with GPIO aggregator
code? In that case it makes sense.

Cc'ing Geert but I don't quite see how this would make sense. :)

Also one thing I'm not sure about re configfs is the interface we use
to read values/set pull i.e. the line attributes in debugfs, do you
think configfs allows this type of attributes?
