That was Greg's (cc'd) greybus stuff entering the staging tree:

$ git rev-list --count --no-merges origin/master..2bbadafbe4ea

I will have a look at what can be done. Normally trees do not grow in
large leaps, this was exceptional. Most often such an increase would
be caused by one tree merging in another (both of which are often in
linux-next) e.g. the drm tree merges 8 other trees that I have and the
net-next tree also merges 8 others.
