A deadlock vulnerability in the Linux kernel scheduler extension (sched_ext) was resolved by changing when ops.dequeue() is invoked relative to DSQ locks. The issue caused self-deadlocks when ops.dequeue() was called while holding a source user DSQ lock, particularly affecting BPF schedulers that lock the source user DSQ during iteration. The fix moves the ops.dequeue() call to after the DSQ unlock to prevent deadlocks and ensures the callback is invoked exactly once.
