Hmm. We have a fairly widespread convention that pointers to structs
can be separately typedef'd as Foo where the underlying struct is
typedef FooData. This isn't following that naming convention though,
and right offhand "FooP" doesn't seem an improvement over "Foo *".

I also notice that there are many more uses of VacAttrStats * than
VacAttrStatsP, so the collective vote about which notation is clearer
seems already taken.

If it bugs you, I'd suggest getting rid of typedef VacAttrStatsP
altogether and using VacAttrStats * everywhere. It's surely not
too important though...
