That's what should be asked of printk().

And as long as we're not going to depricate printk() -- any attempt
thereof will meet with fierce resistance from yours truly -- its all a
futile exercise at best, and breaking scripts habits and patches at
worst.

I might be strange, but if I want to print something in C I write
print[fk]() and be done with it, there's no reason what so ever to
introduce fancy wankery for this.

We try to stick to ANSI-C as much as possible, we've got
kalloc,kfree,strcmp,strnlen and all the other 'regular' C bits,
deviating from that serves no purpose but seed confusion.

If driver folks feel the need for dumb-ass wrappers because they can't
write printk() then maybe, otoh if they can't do that, then wtf are they
doing writing drivers anyway.

But I feel this has no place in the core kernel at all, esp when its
getting in the way of things without offering a single benefit.
