The extra things I want can stay in a devel branch until notifiers get
cleaned up and it will only be a few patches which aren't very likely
to cause conflicts when it gets exported for linux-next or other
testing branches.

Yeah, sure.  So, two patchsets.  One for sched/core doing pure
reorganization without any functional changes.  The other for
sched/notifier (or whatever name you would prefer) which is purely for
development and testing and will not be pushed to Linus unless it
receives notifier framework cleanup.  wq#for-next will pull from
sched/notifier and be exported to linux-next but it will never be
submitted to Linus until sched/notifier is cleaned up.  Am I
understanding it correctly?

Thanks.
