If I take a hunk of a random reverted patch and add the S-o-b of the big patch's author, can I really assume the original author "acks" the result? I would expect that in most cases they don't. (And if they do, there is no way to record it, because the usual way of adding an Ack is blocked as there is already a S-o-b?) *shrug* Uwe -- Pengutronix e.K. | Uwe Kleine-König | Industrial Linux Solutions | https://www.pengutronix.de/ |
