Aha! And I am not sure why I put that in my #linux-next branch. That
is not good - thanks for identifying the cause of that patch being
dropped, and I am sorry for pushing it there without getting the
proper Acks.

Of course.

If you have some time, can you tell me what other times this has
caused trouble? I remember Jeremy did a mistake some time ago
(so patch with a very very old time date) that screwed up something.

And .... oh, the compile time one that Randy found and it did not get
fixed for some very emberassingly long time. If I remember right that was
in Jeremy's tree (xen) - not mine (xen-two):
http://marc.info/?i=20110804193534.GB12729@elte.hu

We do have _two_ Xen trees (xen and xen-two) - which is not making things
easier to figure out who is at fault for what.

You would not have a good overview of maintainer practices so that both
me and Jeremy can refresh our memory of what to do and especially
what _not_ to do?
