What earlier question? The "how could this happen" one?

Dmitry already answered that one - are you perhaps missing the emails?

linux-next has apparently not worked at all for over a month. So it
got no testing at all, and thus also all the gup patches got no
testing in linux-next.

Only when they hit my tree, did they start getting testing. Not
because my tree is the only thing getting tested, but because my tree
is the only tree that _works_.
