Pull sched_ext updates from Tejun Heo:
- Improve recovery from misbehaving BPF schedulers.
When a scheduler puts many tasks with varying affinity restrictions
on a shared DSQ, CPUs scanning through tasks they cannot run can
overwhelm the system, causing lockups.
Bypass mode now uses per-CPU DSQs with a load balancer to avoid this,
and hooks into the hardlockup detector to attempt recovery.
Add scx_cpu0 example scheduler to demonstrate this scenario.
- Add lockless peek operation for DSQs to reduce lock contention for
schedulers that need to query queue state during load balancing.
