you should NEVER make fixes depend on cleanups. It should be the other
way around :-) First fixes, then cleanups. The reason is that fixes can
get accepted during -rc cycle, but cleanups must wait until the next
merge window.

Please fix up your patches, otherwise I'll have to apply the entire
series for v4.17
