What this means is the CPU executing the atomic Directions mustn't respond to any cache coherency protocol messages for this cacheline from the imply time. When the devil is in the main points of how This can be executed, at-least it offers us a psychological product

as whenever they do - they probable in fact use the store buffer, but they flush it and also the instruction pipeline before the load and look forward to it to empty soon after, and also have a lock on the cacheline they get as component o the load, and launch as Portion of the store - all to be sure that the cacheline doesn't disappear in between and that no-one else can see the store buffer contents while this is going on.
