set_wmb(var, value) is not used anywhere in the kernel. And it doesn't do anything special but shorten the typing of:
var = value; wmb(); Which the above is much more readable, and thus set_wmb is just something to confuse developers even more. So this patch series removes set_wmb from the kernel. It's not currently used in the kernel, and any out-of-kernel branch can easily replace it. So there should be no harm in removing it. The first patch removes it from Documentation/memory-barriers.txt and the second patch does a sweep through all the architectures to get rid of it. All archs do the above code except ia64 and sparc which do a mb() instead. But regardless, it's still not used. -- Steve - To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
