thank you for your reply.
is it suitable to help me send patch ?
I am not quite expert about it, and also no releative environments.
if you will:
please mark me as Reported-by in your patch.
need not cc to me:
I am not reviewer, so I am not suitable to review another maintainers
patch
else
it is my duty to send the relative patch (although it seems not a good idea)
thanks.
