Hi Catalin, 4.10-rcX is good enough but I also need to be sure that
when merge window will be opened I will not find my series broken due
to conflicts, because merge window is only 2 weeks, and there's no
much time to investigate and fix all bugs properly.

Anyway, linux-next is what I need, as Chris mentioned.
