Futexes:
- Use runtime constants for futex_hash computation
(K Prateek Nayak, Peter Zijlstra)
- Optimise the size check get_futex_key() (Sebastian Andrzej Siewior)
- Avoid private hash use-after-free on final put (Felix Hoffmann)
- Tell kmemleak we're not leaking __futex_queues (Peter Zijlstra)
Rust integration updates:
- Implement refcounted interrupt disable and SpinLockIrq for Rust
(Boqun Feng, Heiko Carstens, Joel Fernandes, Lyude Paul)
- Rust sync: add helpers for mb, dma_mb and friends;
add generic memory barriers and use LKMM atomics
instead of Rust atomics in the revocable code (Gary Guo)
- Add abstraction and integrate synchronize_rcu() (Philipp Stanner)
Lock debugging:
- Add qspinlock contended_release tracepoint
(Dmitry Ilvokhin, Peter Zijlstra)
- Enable the printing of held locks of remote running tasks and print
task CPU (Ingo Molnar)
- percpu-rwsem: Annotate intentional data race in readers_active_check()
