I have just finished reading over this and must say that this is excellent.
If I would have started reading on this topic from this doc and then move
to other in-tree docs, including memory-barriers.txt, I would
have had much less issues/questions and it would be much less of a bumpy
read.

Is there any plan to include it into official kernel doc tree? I really think it
would be very helpful for others also even basically to explain the notations, properties
and language people talk about these issues and give examples.

I will try to improve a bit the new doc I have previously sent a patch for in the
spirit of this reading.


Best Regards,
Elena.
