It gets expanded internally into all of the pr_*() calls.

This is exactly how it can be used, and there is much
precedent for this now.

It was an unspecified printk() so Joe's conversion is equal
and that's a good way for him to have made these changes.

If we want to mark this as KERN_ERR or whatever, that's entirely
a seperate change.

I think your objections to Joe's changes are completely uncalled
for and his changes were good ones.
