This stuff ain't whitespace.

I'll have to respectfully disagree with you.  For ext4, as far as I am
concerned, changing printk(KERN_INFO, ...) to pr_info(...) is *purely*
a whitespace-level change.

Joe, if everything did change, what difference would it make?

just being a consistant style doesn't matter much, but if there is some 
functionality that would be possible with pr_info(...) that would not be 
possible with printk(KERN_INFO, ...), there may be more reason to change.
