- Tighten up the sys_futex_requeue() ABI a bit, to disallow
dissimilar futex flags and potential UaF access. (Peter Zijlstra)
- Fix UaF between futex_key_to_node_opt() and vma_replace_policy()
(Hao-Yu Yang)
- Clear stale exiting pointer in futex_lock_pi() retry path,
which bug triggered a warning (and potential misbehavior)
in stress-testing. (Davidlohr Bueso)
