Should this be turned into a static inline calling
kfree_skb_with_reason() now? BTW you should drop the
'_with'.
 

I thought about it before, but I'm a little afraid that some users may trace
kfree_skb() with kprobe, making it inline may not be friendly to them?

Hm, there is a bpf sample which does that, but that's probably 
not commonly used given there is a tracepoint. If someone is 
using a kprobe they can switch to kprobing kfree_skb*reason().
