- An error raised by a BPF program before the scheduler finished enabling was consumed by the disable path's pre-enable shortcut, leaving a running scheduler that couldn't be disabled and was later freed while in use. - Two compat kfuncs dereferenced a NULL scheduler when handed an exited or idle task, oopsing the kernel. - Keep-running decisions in the dispatch path used the root scheduler's flags for tasks belonging to a sub-scheduler, causing warnings and stalls. - Schedulers with their own CPU ID mapping had no way to learn which IDs are online. Add a kernel-maintained online mask to plug the hole. - Cgroup idle state: the initial cpu.idle state wasn't passed on cgroup init and same-value rewrites delivered spurious callbacks. - Example scheduler fixes for a reenqueue loop on attach, placements on CPUs without effective grants, stalled partition work and stale idle tracking. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCaql+vQ4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGUTxAP9mhhePmghF/aq6SzeaVGeUXtclXRAGE1EAqea6 kzh50AEAiWXtFQu9dAF3EaXTWJkEJZkJUs0AO0wEXgghC0py9gY= =gcDW -----END PGP SIGNATURE----- Merge tag 'sched_ext-for-7.3-rc3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext fixes from Tejun Heo: - An error raised by a BPF program before the scheduler finished enabling was consumed by the disable path's pre-enable shortcut, leaving a running scheduler that couldn't be disabled and was later freed while in use. - Two compat kfuncs dereferenced a NULL scheduler when handed an exited or idle task, oopsing the kernel. - Keep-running decisions in the dispatch path used the root scheduler's flags for tasks belonging to a sub-scheduler, causing warnings and stalls. - Schedulers with their own CPU ID mapping had no way to learn which IDs are online.
