Well, IIUC he's the one initiating the whole thing, no?

Nothing. I like competition. But why push it into the kernel? It's not a kernel, it's not a library the kernels needs for internal stuff. So why would it have to be in there?

In Ingo's reasoning, the next step would be to rewrite glibc and put it into the kernel tree, because we end up adding syscalls so adding them to the in-kernel libc with the same commit would be a lot easier and cleaner.
