Subject: [GIT PULL] scheduler changes for v6.4
Date: Thu, 27 Apr 2023 22:51:05 +0200 [thread overview]
Message-ID: <ZErgOfOLrBwluTbd@gmail.com> (raw)
Linus,
Please pull the latest sched/core git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-2023-04-27
# HEAD: f31dcb152a3d0816e2f1deab4e64572336da197d sched/clock: Fix local_clock() before sched_clock_init()
Scheduler changes for v6.4:
- Allow unprivileged PSI poll()ing
- Fix performance regression introduced by mm_cid
- Improve livepatch stalls by adding livepatch task switching to cond_resched(),
this resolves livepatching busy-loop stalls with certain CPU-bound kthreads.
- Improve sched_move_task() performance on autogroup configs.
- On core-scheduling CPUs, avoid selecting throttled tasks to run
- Misc cleanups, fixes and improvements.
Thanks,
Ingo
