I don't mind, in general, but I'm a bit hesitant. we want to have
automatic printk throttling (printk delay basically) and we need
some of those printk-internal *_seq numbers to see how far consoles
are behind the logbuf. so either we need to 'un-static' those *_seq
and extern them in delay.c or simply keep printk-delay machinery in
printk.c and add the new function.

// p.s. I'll take a look at the patch a bit later. I'm on a sick leave now.
