> Note that KERN_foo in the middle of strings, even after a newline are
> preserved in the output.  So:
> 
>                 printk(KERN_WARNING "BUG: Your driver calls ioremap() on system memory.  This leads\n"
>                        KERN_WARNING "to architecturally unpredictable behaviour on ARMv6+, and ioremap()\n"
>                        KERN_WARNING "will fail in the next kernel release.  Please fix your driver.\n");
> 
> results in <4>'s appearing on the console.  I've always written code
> over the last 15 years assuming that after any newline in printk output,
> the log level gets reset and so needs a new log level specifier.
> 
> Sounds like this is something which needs auditing as a result of your
> change, and sounds like its something that kernelnewbies people could
> do.  My own greps haven't revealed any cases though.
