Umm... We always explicitly comment out the shift of 0x10, 0x20, ...,
IMO, we'd better move the comments to the correct place instead of
change it to something like 0x28.

Thanks,
Joseph

Hi Zhonghua and Jospeh,

I'm afraid that it can't be easy to find the offest 0x20 since 
::db_signature only occupy 8 bytes.

Thanks,
Changwei
