Yes, that should be it.

So why not put the majority of this through sched.git, then when my
sysfs changes go in at the beginning of the .25 merge cycle, you can
then add the sysfs changes through your tree or anywhere else.

Unless you are relying on the sysfs changes for this whole feature, and
without them it just doesn't make any sense at all?
