Linus Torvalds f087b0bad4 Merge tag 'locking-urgent-2026-03-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull futex fixes from Ingo Molnar:

 - 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
   triggered a warning (and potential misbehavior) in stress-testing
   (Davidlohr Bueso)

* tag 'locking-urgent-2026-03-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  futex: Clear stale exiting pointer in futex_lock_pi() retry path
  futex: Fix UaF between futex_key_to_node_opt() and vma_replace_policy()
  futex: Require sys_futex_requeue() to have identical flags
