    Yes, precisely. This requirement has been documented in
    SubmittingPatches for several months now. More details here:

    Casey, *please* don't submit a patch for a system call without also
    providing a test program, and some attempt at userspace documentation.
    (Andi already pointed this out. From my POV, I don't need you to
    write a full blown man page -- if you send me the text, I'll do the
    *roff stuff. But that text should accompany the patch that implements
    the syscall.)
