Sure. I made it a WARN_ON_ONCE(), but then always just printed the
pf/hooknum. It's all over the map:
reg->pf=2 and reg->hooknum=4
reg->pf=2 and reg->hooknum=2
reg->pf=2 and reg->hooknum=3
reg->pf=10 and reg->hooknum=4
reg->pf=10 and reg->hooknum=2
reg->pf=10 and reg->hooknum=3
reg->pf=7 and reg->hooknum=1
reg->pf=7 and reg->hooknum=2
reg->pf=7 and reg->hooknum=3
reg->pf=2 and reg->hooknum=0
reg->pf=2 and reg->hooknum=3
reg->pf=2 and reg->hooknum=0
reg->pf=2 and reg->hooknum=3
reg->pf=2 and reg->hooknum=4
reg->pf=2 and reg->hooknum=4
reg->pf=2 and reg->hooknum=1
reg->pf=2 and reg->hooknum=1
reg->pf=10 and reg->hooknum=0
reg->pf=10 and reg->hooknum=3
reg->pf=10 and reg->hooknum=0
reg->pf=10 and reg->hooknum=3
reg->pf=10 and reg->hooknum=4
reg->pf=10 and reg->hooknum=4
reg->pf=10 and reg->hooknum=1
reg->pf=10 and reg->hooknum=1
reg->pf=7 and reg->hooknum=3
reg->pf=7 and reg->hooknum=4
reg->pf=7 and reg->hooknum=0
reg->pf=2 and reg->hooknum=4
reg->pf=2 and reg->hooknum=2
reg->pf=2 and reg->hooknum=3
reg->pf=10 and reg->hooknum=4
reg->pf=10 and reg->hooknum=2

reg->pf=2 and reg->hooknum=0
reg->pf=2 and reg->hooknum=3
reg->pf=2 and reg->hooknum=0
reg->pf=2 and reg->hooknum=3
reg->pf=2 and reg->hooknum=4
reg->pf=2 and reg->hooknum=4
reg->pf=2 and reg->hooknum=1
reg->pf=2 and reg->hooknum=1
reg->pf=10 and reg->hooknum=0
reg->pf=10 and reg->hooknum=3
reg->pf=10 and reg->hooknum=0
reg->pf=10 and reg->hooknum=3
reg->pf=10 and reg->hooknum=4
reg->pf=10 and reg->hooknum=4
reg->pf=10 and reg->hooknum=1
reg->pf=10 and reg->hooknum=1
reg->pf=7 and reg->hooknum=3
reg->pf=7 and reg->hooknum=4
reg->pf=7 and reg->hooknum=0
and putting that through "sort -n" and "uniq -c", I get:
4 reg->pf=10 and reg->hooknum=0
4 reg->pf=10 and reg->hooknum=1
2 reg->pf=10 and reg->hooknum=2
6 reg->pf=10 and reg->hooknum=3
6 reg->pf=10 and reg->hooknum=4
4 reg->pf=2 and reg->hooknum=0
4 reg->pf=2 and reg->hooknum=1
2 reg->pf=2 and reg->hooknum=2
6 reg->pf=2 and reg->hooknum=3
6 reg->pf=2 and reg->hooknum=4
2 reg->pf=7 and reg->hooknum=0
2 reg->pf=7 and reg->hooknum=1
2 reg->pf=7 and reg->hooknum=2
4 reg->pf=7 and reg->hooknum=3
which doesn't look much better. But clearly there's a lot of those
"try to unregister stuff that you can't even find".
Maybe it tells you something.
