[PATCH v3 00/11] Introduce cmpxchg128() – aka. the demise of cmpxchg_double() (Peter Zijlstra)

https://lkml.kernel.org/r/20230515075659.118447996@infradead.org

This patchset introduces an alternative for cmpxchg_double(), namely cmpxchg128(), and replace the old usages of cmpxchg_double(). This is because Linus hates cmpxchg_double()[1].
