Sorry, I think that won't work since the function is _get_osf_handle
and it works the other way round.
You could try if replacing FILE_FLAG_RANDOM_ACCESS (appears at least in
device.c) with 0 or FILE_FLAG_SEQUENTIAL_SCAN makes a difference,
the latter one might behave badly e.g. while seeking though.
