I think that _all_ of these items can find use in userspace, if they are usable with glibc's threading implementation and the other userspace issues that would be involved.
I for one would love to be able to use lightweight rwsems and spinlocks in an application I'm working on, but it's entirely userspace and it would be impossible for _me_ to pick out this code from the kernel tree and make it work on any architecture that I don't have here (which is all of them except x86 <G>). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
