Pull sched_ext fixes from Tejun Heo: - The task ownership check in the dispatch queue move operation raced against the task exiting or moving to a different sub-scheduler, spuriously triggering scheduler aborts. Fix by moving the check under the queue lock - The cgroup bandwidth change callback runs in a sleepable context but sleepable implementations were rejected at load time. Allow them and add a marker so userspace can detect the capability - Sync tooling headers with the scx repo for accumulated compatibility improvements - Example scheduler fixes: ignored timer re-arm failures and vtime credit loss on cgroup migration - Documentation and comment fixes * tag 'sched_ext-for-7.3-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext: sched_ext: Fix missing @slice and @vtime descriptions in finish_dispatch() kernel-doc sched_ext: Fix several comment issues sched_ext: Check bpf_timer_start return values in scx_qmap sched_ext: Fix vtime delta loss in scx_flatcg cgroup migration sched_ext: Fix timer pinning and return value in scx_central docs/sched_ext: document that cgroup CPU knobs are scheduler-dependent sched_ext: Fix spurious aborts in scx_bpf_dsq_move() on ownership change races sched_ext: Sync common and compat headers from the scx repo sched_ext: Sync tools autogen enum headers from the scx repo Docs/admin-guide/cgroup-v2: document BPF scheduler callbacks for cpu.max and cpu.idle sched_ext: Fix nonexistent field in sched-ext.rst example sched_ext: Allow ops.cgroup_set_bandwidth() to be sleepable
