McKenney Thanks, I think I'll cut the thing into a number of smaller patches with identical end result. Will (hopefully) post a full new series tomorrow somewhere. I was thinking like: 1 - aggressively employ asm-generic/barrier.h 2 - Reformulate _The_ document to ACQUIRE/RELEASE 3 - add the new store/load thingies That should hopefully be slightly easier to look at.
