    Hm, no. I admit to having improved the process of compilation
    somewhat; I compiled only the affected files, or in case a CONFIG
    prevents a file from being built, the complete parent directory. I
    find that this works well in practice; the compiler usually warns
    about implicit declarations (which would otherwise show up as linker
    errors), so there is no need to link everything. (Sadly, this is not
    true when declarations are provided regardless of definition -- I
    think this is actually a case against putting declarations outside

    Well, it's still somewhat emberassing to submit patches that don't compile :-)

    This patch was also a typical error scenario; I introduce the call of
    a function which requires the inclusion of a new header, one which
    seemingly depends on a particular config option (lockdep). So I simply
    wanted to be sure myself -- and then I might as well put it in the
    e-mail. That also implicitly means that I did not boot test it at all.
    (Because, yeah, what it actually DOES should be fairly obvious.)

    Thanks, though! It's really nice to know the world's not coming to an
    end because of a broken patch ;-)

    disguises that the error is the programmer's own creation."
