Hmm, you are proposing to introduce a second format for the kmsg messages to avoid the need for some more printk wrapper macros. To me it seems that this has two problems: 1) The message tag is for the user of the system. If it does not have a fixed position it gets confusing. 2) The message tag for a driver message usually already includes the driver name, the dev_printk will print it again. This is ugly and reduces the quality of the message.
