Documentation/memory-barriers.txt: Add needed ACCESS_ONCE() calls to memory-barriers.txt The Documentation/memory-barriers.txt file was written before the need for ACCESS_ONCE() was fully appreciated. It therefore contains no ACCESS_ONCE() calls, which can be a problem when people lift examples from it. This commit therefore adds ACCESS_ONCE() calls. Signed-off-by: Paul E.
