NAK.

This is likely purely a taste thing, but I completely fail to see how this:

is a good thing at all.  Maybe you could convince me to change my mind about
it but I dislike the resuling uglyness, so I will need a good technical
reason to even consider it.

Why would I want a parameter macro instead of a straightforward bunch of
#defines ?  It is not like the #defines are harder to understand than this
pr_fmt thing.

I am with Peter Zijlstra on this one.  I don't want the pr_foo() siliness in
code I maintain.  You could perhaps convince me to change what is inside the
printk(), but the fact that my printk helpers end with "_printk" is not a
coincidence.
