    I saw this warning with certain GCC versions for several kernel
    cycles, so it's not any recent change that triggers this and it is
    not a regression.

    GCC is simply wrong here - i have posted a workaround for that but
    it is too ugly to be merged upstream.

    This patch regresses on older GCC versions and doesnt really address
    the GCC false positive warning either, it just removes the inline
    function that triggers the warning.
