I fully second this. The main problem with
Documentation/memory-barriers.txt is that it jumps from "easy to follow"
to "blow your head" parts is just too quick. On the other hand the above
explanation builds the picture from basics and piles up new layers on
top of previous. So I found it much more easier to grasp. I cannot
really speak for the correctness in all aspects but it certainly makes a
lot of sense to me. If you are really interested then feel free to add.
