> CS only serializes agains CS, It serializes happily against all the CS variations, TS, and the newer interlocked-update instructions like ASI, LAA, and so on. And there are cases where a simple ST or the like can interoperate usefully with CS. For instance, if you update a counter with CS, it is safe to zero it with ST.
