Subject: [GIT PULL] locking changes for v6.9
Date: Mon, 11 Mar 2024 12:20:12 +0100 [thread overview]
Message-ID: <Ze7o7FAK8QkRLg7o@gmail.com> (raw)
Linus,

# HEAD: ce3576ebd62d99f79c1dc98824e2ef6d6ab68434 locking/rtmutex: Use try_cmpxchg_relaxed() in mark_rt_mutex_waiters()
Locking changes for v6.9:
- Micro-optimize local_xchg() and the rtmutex code on x86
- Fix percpu-rwsem contention tracepoints
- Simplify debugging Kconfig dependencies
- Update/clarify the documentation of atomic primitives
- Misc cleanups
Thanks,
Ingo
