    Linus Torvalds rarely writes significant amounts of kernel code these days, so the merging
    of a 48-part patch series from him is an unusual event. This series,
    destined for the 7.4 kernel release, performs some long-delayed kernel
    cleanup by removing a couple of the primitives used to access user-space memory from the kernel. What was once a best practice has long been superseded,
    but it can take time for such changes to work their way through a body of
    code this large.
