That's changed behavior.
Which is an improvement too. I very much doubt a single app will change because of this.
printk_emit() does parse the leading \0014, and then skips over it, removing it from the output stream. printk_emit() then throws away the resulting level because devkmsg_writev() did not pass in level==-1.
I'm glad you know how it works now.
cheers, Joe
