The existing code in Linux doesn't seem to care about mitigating notifications -- xenbus is supposed to exchange small amount of information anyway so whether a few more notifications are sent is not essential. I think it would be better if we follow something that works at this stage. The use of ring macro can be considered an improvement but not essential to fix the bug.

My reason for suggesting it was more that we trust that those macros are already correct, compared with needing to reason from scratch about the open coded version used in this code which is what appeared to be going on.
