Hello, Kosaki-san

Thanks for your comments for this patch,
I'll merge your and other people's comments and send a V2.

About line exceed 80 characters, I do checkpatch before send, and I know that
lines in TP_STRUCT__entry are too long.
It it because I use similar format with other TRACE_EVENT definition.
Actually, I don't know why we need to add prefix and postfix TABs, and is it
necessary to use tab to make alignment for each fields.
Who can give me teach? or I will use different format to fix this 80-char problem.

Thanks
Zhaolei
