Hi Arnd, Kevin, Olof:
If it's not too late for v4.2, can you please pull in this patch.
Sorry, too late for v4.2.
If this is actually fixing a regression (it doesn't look like it to me
at first glance), please resend as a fix for v4.2-rc explaining the
regression that is being fixed. Otherwise, please add it to your queue
for v4.3.
Thanks,
Kevin
