Hi.
I think that the change above is not related to the fix below.
I think it should be in a separate patch targeted at net-next.
And as net-next is currently closed it should be posted once it
reopens, after the 27th May.
The changes below look good to me.
I suggest resending only those changes, targeted at net, as v3.
Thanks.
