Well, I don't NACK the patch, I just want to keep pf/pF in vsprintf(),
that's it. Yes, checkpatch warns about pf/pF uses, becuase we don't want
any new pf/pF in the code - it's rather confusing to have both pf/pF and
ps/pS -- but I don't necessarily see why would we want to mess up with
parisc/hppa/ia64 people using pf/pF for debugging purposes, etc. I'm not
married to pf/pF, if you guys insist on complete removal of pf/pF then so
be it.
