Because the source are in the same git tree as the kernel does not require the source to be considered a kernel. You are talking from the wrong assumption that because the source live in the git tree of the kernel it has hard dependencies on that particular kernel. This is wrong. There is the same requirements about being backward/forward compatible as if the tool lived in a git tree outside the kernel. What we achieve by letting the userspace tools live inside the kernel are: - Kernel hacker tools are avaialble for the kernel hackers - The tools are easy to upgrade when we add new stuff to the kernel - We know that the updates are done upstream - We have the kernel base of developers at easy reach, no need to build up a new development community Sam -- 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/
