Patch series logistics:
- No objections from the scheduler side, this feature looks pretty useful.
- Certain patches are incomplete, others are noted as being merged
separately, so I presume you'll send an updated/completed series
eventually?
- We can merge this via the scheduler tree I suspect, as most callbacks
affected relate to tip:sched/core and tmp:smp/core - but if you have
some other preferred tree that's fine too.
Thanks,
