# Merge: 42dec9a936e7 2ea46c6fc945
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'sched-core-2021-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull scheduler updates from Ingo Molnar:
#     
#      - Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and
#        debugfs interfaces to a unified debugfs interface.
#     
#      - Signals: Allow caching one sigqueue object per task, to improve
#        performance & latencies.
#     
#      - Improve newidle_balance() irq-off latencies on systems with a large
#        number of CPU cgroups.
#     
#      - Improve energy-aware scheduling
#     
#      - Improve the PELT metrics for certain workloads
#     
#      - Reintroduce select_idle_smt() to improve load-balancing locality -
#        but without the previous regressions
#     
#      - Add 'scheduler latency debugging': warn after long periods of pending
#        need_resched. This is an opt-in feature that requires the enabling of
#        the LATENCY_WARN scheduler feature, or the use of the
#        resched_latency_warn_ms=xx boot parameter.
#     
#      - CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix
#        remaining balance_push() vs. hotplug holes/races
#     
#      - PSI fixes, plus allow /proc/pressure/ files to be written by
#        CAP_SYS_RESOURCE tasks as well
#     
#      - Fix/improve various load-balancing corner cases vs. capacity margins
#     
#      - Fix sched topology on systems with NUMA diameter of 3 or above
#     
#      - Fix PF_KTHREAD vs to_kthread() race
#     
#      - Minor rseq optimizations
#     
#      - Misc cleanups, optimizations, fixes and smaller updates
#
