I think it would be lovely to get linux-next back eventually, but it
sounds like it's just too noisy right now, and yes, we should have a
baseline for the standard tree first.

But once there's a "this is known for the baseline", I think adding
linux-next back in and then maybe even have linux-next simply just
kick out trees that cause problems would be a good idea.

Right now linux-next only kicks things out based on build issues (or
extreme merge issues), afaik. But it *would* be good to also have
things like syzbot do quality control on linux-next.

Because the more things get found and fixed before they even hit my
tree, the better.
