- Fix starvation of scx_enable() under fair-class saturation by offloading the enable path to an RT kthread. - Fix out-of-bounds access in idle mask initialization on systems with non-contiguous NUMA node IDs. - Fix a preemption window during scheduler exit and a refcount underflow in cgroup init error path. - Fix SCX_EFLAG_INITIALIZED being a no-op flag. - Add READ_ONCE() annotations for KCSAN-clean lockless accesses and replace naked scx_root dereferences with container_of() in kobject callbacks. - Tooling and selftest fixes: compilation issues with clang 17, strtoul() misuse, unused options cleanup, and Kconfig sync. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCaadTZA4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGdf9AQDmsZ8Y3uOJV/5K5RuEoo6SDPmCjr+JXPZu45kD +UBj3wD9F8DPq+g+KnD7jILhqUdOTePhhNrVYbVw3e1x29EYBQ0= =nRTC -----END PGP SIGNATURE----- Merge tag 'sched_ext-for-7.0-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext fixes from Tejun Heo: - Fix starvation of scx_enable() under fair-class saturation by offloading the enable path to an RT kthread - Fix out-of-bounds access in idle mask initialization on systems with non-contiguous NUMA node IDs - Fix a preemption window during scheduler exit and a refcount underflow in cgroup init error path - Fix SCX_EFLAG_INITIALIZED being a no-op flag - Add READ_ONCE() annotations for KCSAN-clean lockless accesses and replace naked scx_root dereferences with container_of() in kobject callbacks - Tooling and selftest fixes: compilation issues with clang 17, strtoul() misuse, unused options cleanup, and Kconfig sync * tag 'sched_ext-for-7.0-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext: sched_ext: Fix starvation of scx_enable() under fair-class saturation sched_ext: Remove redundant css_put() in scx_cgroup_init() selftests/sched_ext: Fix peek_dsq.bpf.c compile error for clang 17 selftests/sched_ext: Add -fms-extensions to bpf build flags tools/sched_ext: Add -fms-extensions to bpf build flags sched_ext: Use READ_ONCE() for plain reads of scx_watchdog_timeout sched_ext: Replace naked scx_root dereferences in kobject callbacks sched_ext: Use READ_ONCE() for the read side of dsq->nr update tools/sched_ext: fix strtoul() misuse in scx_hotplug_seq() sched_ext: Fix SCX_EFLAG_INITIALIZED being a no-op flag sched_ext: Fix out-of-bounds access in scx_idle_init_masks() sched_ext: Disable preemption between scx_claim_exit() and kicking helper work tools/sched_ext: Add Kconfig to sync with upstream tools/sched_ext: Sync README.md Kconfig with upstream scx selftests/sched_ext: Remove duplicated unistd.h include in rt_stall.c tools/sched_ext: scx_sdt: Remove unused '-f' option tools/sched_ext: scx_central: Remove unused '-p' option selftests/sched_ext: Fix unused-result warning for read() selftests/sched_ext: Abort test loop on signal |
