- Revert the printk format based wchan() symbol resolution as it can leak the raw value in case that the symbol is not resolvable. - Make wchan() more robust and work with all kind of unwinders by enforcing that the task stays blocked while unwinding is in progress. - Prevent sched_fork() from accessing an invalid sched_task_group - Improve asymmetric packing logic - Extend scheduler statistics to RT and DL scheduling classes and add statistics for bandwith burst to the SCHED_FAIR class. - Properly account SCHED_IDLE entities - Prevent a potential deadlock when initial priority is assigned to a newly created kthread. A recent change to plug a race between cpuset and __sched_setscheduler() introduced a new lock dependency which is now triggered. Break the lock dependency chain by moving the priority assignment to the thread function. - Fix the idle time reporting in /proc/uptime for NOHZ enabled systems. - Improve idle balancing in general and especially for NOHZ enabled systems. - Provide proper interfaces for live patching so it does not have to fiddle with scheduler internals. - Add cluster aware scheduling support. - A small set of tweaks for RT (irqwork, wait_task_inactive(), various scheduler options and delaying mmdrop) - The usual small tweaks and improvements all over the place -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmF/OUkTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoR/5D/9ikdGNpKg9osNqJ3GjAmxsK6kVkB29 iFe2k8pIpWDToWQf/wQRGih4Yj3Cl49QSnZcPIibh2/12EB1qrrW6iSPJkInz8Ec /1LS5/Vewn2OyoxyXZjdvGC5gTXEodSbIazASvX7nvdMeI4gsAsL5etzrMJirT/t aymqvr7zovvywrwMTQJrGjUMo9l4ewE8tafMNNhRu1BHU1U4ojM9yvThyRAAcmp7 3Xy49A+Yq3IgrvYI4u8FMK5Zh08KaxSFjiLhePGm/bF+wSfYmWop2TP1jY05W2Uo ti8hfbJMUoFRYuMxAiEldkItnc0wV4M9PtWZZ/x+B71bs65Y4Zjt9cW+rxJv2+m1 vzV31EsQwGnOti072dzWN4c/cZqngVXAjaNtErvDwJUr+Tw1ayv9KUvuodMQqZY6 mu68bFUO2kV9EMe1CBOv51Uy1RGHyLj3rlNqrkw+Xp5ISE9Ad2vhUEiRp5bQx5Ci V/XFhGZkGUluh0vccrdFlNYZwhj8cZEzkOPCnPSeZ+bq8SyZE6xuHH/lTP1CJCOy s800rW1huM+kgV+zRN8adDkGXibAk9N3RtVGnQXmuEy8gB9LZmQg+JeM2wsc9B+6 i0gdqZnsjNAfoK+BBAG4holxptSL8/eOJsFH8ZNIoxQ+iqooyPx9tFX7yXnRTBQj d2qWG7UvoseT+g== =fgtS -----END PGP SIGNATURE----- Merge tag 'sched-core-2021-11-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler updates from Thomas Gleixner: - Revert the printk format based wchan() symbol resolution as it can leak the raw value in case that the symbol is not resolvable. - Make wchan() more robust and work with all kind of unwinders by enforcing that the task stays blocked while unwinding is in progress. - Prevent sched_fork() from accessing an invalid sched_task_group - Improve asymmetric packing logic - Extend scheduler statistics to RT and DL scheduling classes and add statistics for bandwith burst to the SCHED_FAIR class. - Properly account SCHED_IDLE entities - Prevent a potential deadlock when initial priority is assigned to a newly created kthread.
