Hi Yuichi,

Thanks for the patch! 

However, I need to say some coding style problem first;) I didn't say
this before, so it seems a little bit messy and will confuse a lot of
contributors and users, sorry for the inconvenience;)  

Now I'd like to say that booth is inclined to use the Linux kernel
coding style. For the existing problems in the booth repository, I'm
going to cleanup the code soon. For the newly submitted patches, I'd
like them to obey the kernel coding style.

So Yuichi, before I looked at this patch in more detail, could you use
the checkpatch.pl (in kernel source tree) script to check the patch
first?;)

Thank you very much!

Regards,
Jiaju
