# HEAD: feff2e65efd8d84cf831668e182b2ce73c604bbb sched/deadline: Unthrottle
PI boosted threads while enqueuing
Scheduler changes for v5.10:
- Reorganize & clean up the SD* flags definitions and add a bunch
of sanity checks. These new checks caught quite a few bugs or at
least inconsistencies, resulting in another set of patches.
- Rseq updates, add MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ
- Add a new tracepoint to improve CPU capacity tracking
- Improve overloaded SMP system load-balancing behavior
- Tweak SMT balancing
- Energy-aware scheduling updates
- NUMA balancing improvements
- Deadline scheduler fixes and improvements
- CPU isolation fixes
- Misc cleanups, simplifications and smaller optimizations.
Thanks,
Ingo
