List,

I have C question on skbuff.h.
skb->_skb_dst is defined as unsigned long and dst_entry is struct.

Why strct dst_entry casts unsigned long skb->_skb_dst?

See below

static inline struct dst_entry *skb_dst(const struct sk_buff *skb)
{
	return (struct dst_entry *)skb->_skb_dst;
}

Appreciate any answer!
