And just for the record - I think the reason why I didn't feel like
doing a tree wide pf->ps conversion was that some of those pf->ps
printk-s could end up in -stable backports [sure, no one backports
print out changes, but a print out can be part of a fix which gets
backported, etc]. So I just decided to stay away from this. IIRC.
