useless comments, they aren't becoming useful after prettifying, right. ;-)

KERN_NOISE, it's pretty hard to not notice transformation of
bitmask to string representation, isn't it?

For the record, string splitting occasionaly makes grepping much more annoying:
grep. nothing? kernel in bugreport definitely spit it! [minute later]
Oh, I need to grep for smaller strings.

Oh, c'mon!
And my pet peeve with checkpatch.pl crap: why does it force me to _add_
KERN_ markers when my patch changes code leaving printk intact, because
the patch wasn't about printk at all?
Or more philosophically, why a tool which doesn't parse C compiler-style
suddenly starts making suggestions on how C code should look like?
