# Merge: a2f0e7eee134 7c4a5b89a0b5
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Mon Feb 20 17:41:08 2023 -0800

#     Merge tag 'sched-core-2023-02-20' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull scheduler updates from Ingo Molnar:
#     
#      - Improve the scalability of the CFS bandwidth unthrottling logic with
#        large number of CPUs.
#     
#      - Fix & rework various cpuidle routines, simplify interaction with the
#        generic scheduler code. Add __cpuidle methods as noinstr to objtool's
#        noinstr detection and fix boatloads of cpuidle bugs & quirks.
#     
#      - Add new ABI: introduce MEMBARRIER_CMD_GET_REGISTRATIONS, to query
#        previously issued registrations.
#     
#      - Limit scheduler slice duration to the sysctl_sched_latency period, to
#        improve scheduling granularity with a large number of SCHED_IDLE
#        tasks.
#     
#      - Debuggability enhancement on sys_exit(): warn about disabled IRQs,
#        but also enable them to prevent a cascade of followup problems and
#        repeat warnings.
#     
#      - Fix the rescheduling logic in prio_changed_dl().
#     
#      - Micro-optimize cpufreq and sched-util methods.
#     
#      - Micro-optimize ttwu_runnable()
#     
#      - Micro-optimize the idle-scanning in update_numa_stats(),
#        select_idle_capacity() and steal_cookie_task().
#     
#      - Update the RSEQ code & self-tests
#     
#      - Constify various scheduler methods
#     
#      - Remove unused methods
#     
#      - Refine __init tags
#     
#      - Documentation updates
#     
#      - Misc other cleanups, fixes
#
