Grumble.  I have been conveniently been forgetting about that socket.
Similarly we have the user mode helpers to deal with.

For this conversation there is a simple answer.  All of that is in the
kobject layer, and works even when you compile sysfs out of your kernel.
Therefore it is a separate problem.  And sysfs idr tags have nothing
to do with it.

It is most definitely something we need to come back to.  I bet there
are some interesting interactions when you have multiple network devices
with the same name generating events.
