OK, I will send patch v2 for it.
I sent this patch based on Linux next tree, please tell me the tree
location (git address) which I shall base on for sending patch v2.
Thanks.

The request tag provides a concise identification of a SCSI
command, so we should be printing that out for scmd_printk().

Hi all,
this is the second part of my scsi logging update, covering
CDB and sense code printing. With this patchset CDBs and
sense code bytes will be formatted on a single line
(where possible), and prefixed with the device and command
tag.
To ensure CDBs and sense code bytes are not broken up du
SPC-3 defines SERVICE ACTION IN(12) and SERVICE ACTION IN(16).
So rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16 to be
consistent with SPC and to allow for better distinction.

scsi_log_send() would display buffer pointer for higher
logging levels. This is not only of questionable value
but also exposes kernel pointer to userspace, which is
discouraged in some setups. So drop this message
altogether.
