no Ack from Laurent yet? hmm, I'll have to delay this one for the next merge window, sorry. Just as a side note, version changes (v2, v3, v4, v5 above) should comer after the tearline (---) below. We don't need these changes in the commit log, it's just for maintainers to read :-) If we had an ack from Laurent, I'd fix that while applying, but since you're gonna have to resend anyway, please fix that once we get an Ack from Laurent. -- balbi
