Sigh, which part of the "no regressions" policy did you not
understand?

Even if we ignored regressions (which we don't), you'd *STILL*
be wrong: using printk to debug crashes (and to develop code in
general) is one of its earliest and I'd say most important role.

And when do we need printk() output? Most of the time only when
there's a problem with the system - such as a crash.

System logging is an arguably secondary role, and it should not
degrade printk()s primary role.

Your flippant attitude towards printk quality is really sad.

Thanks,

Ingo
