This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read Documentation/stable_kernel_rules.txt
for how to do this properly.

Hi,

     I want to submit the patch to mainline, I feel so ashamed for disturbing you,
you can ignore it....  I have written wrong email.
     Later, when I need, I will read Documentation/stable_kernel_rules.txt first,
thank you anyway.

Regards, AiHua.
