Doing it in userspace makes generating the node description changed
trap simpler?

Hmm... how many places can do sethostname()?  Seems easier to
catch in the kernel than hook every place in userspace.  (Although
there's no kernel hook right now)  I do agree it would be good to
have some idea of how we could generate the "node desc changed"
trap at appropriate times.

What about other drivers? I didn't see ehca in Mike's patch..

ehca doesn't implement modify_device --> can't set node desc anyway.

I just wonder if this is a big pain to do right, what about charsets, IDN,
and ugly details like that?

Does anyone expect to care about non-ASCII node descs?
What can we sensibly do except take what we're given?
