btw. I still believe that it would be helpful (and congruent with the
established norm) to have the version in all patch titles. I do use
threaded view, but inboxes are huge, and everything that helps you
orient yourself is welcome

Helper is for scheduler internal use so lets hide it from DRM drivers
completely.
At the same time we change the method of checking whethere there is
anything in the queue from peeking to looking at the node count.

Is there any particular reason why you want the code in an header
instead of a new .c file?
IMO it is too trivial to warrant emitting a function.
We might want to consider this, since I'd expect that the number of
internal helpers increases over the years.
I actually hope the scheduler code gets smaller and simpler in the
future. In any case the things hidden in sched_internal.h will be easy
to refactor since it will be impossible for drivers to grow a dependency
on them.
