No need to ping, since Rik reviewed it 7 hours ago so the thread has
gotten a bump in our mailboxes.
And anyway this is the merge window, which is the most annoying time to
get pings and one-patch changes. I don't mind at all getting large
series during the merge window, but the small ones definitely can wait a
week or two.
Thanks,
Paolo
