Even changes which cause no functional differences?  It's just
logistics at that point and I'll only be pushing the actual changes
(addition of wakeup/sleep callbacks) to linux-next so that different
stages of workqueue changes can receive some amount of testing.  If
you don't want that in sched development tree, I can maintain a
temporary branch for linux-next testing but I really can't see what
will be the benefit of doing things that way.

Thanks.
