Hi David
Just for my clarification:
We are in the middle of the merge window. What does net-next and net
mean at the moment?
Outside of the merge window, net is patches being collected to go into
the next -rc. net-next is used to collect patches for the next merge
window.
During the merge window, i've seen you collect patches into net-next
and send additional pull requests to Linus. Which is why i based it on
net-next. I did not check, but i assumed net was still on v4.8.0,
waiting for -rc1 to come out. But this assumption seems untrue. During
the merge window does net equate to what Linus has already pulled from
net-next?
Thanks
Andrew
