static __inline struct sk_buff* skb_unshare ( struct sk_buff *  skb, int  pri  ) [static, read] skb_unshare - make a copy of a shared buffer : buffer to check : priority for memory allocation If the socket buffer is a clone then this function creates a new copy of the data, drops a reference count on the old copy and returns the new copy with the reference count at 1. If the buffer is not a clone the original buffer is returned. When called with a spinlock held or from interrupt state must be GFP_ATOMIC NULL is returned on a memory allocation failure. Definition at line 384 of file tcpcore.h. { struct sk_buff *nskb; if(!skb_cloned(skb)) return skb; nskb=skb_copy(skb, pri); kfree_skb(skb); /* Free our shared copy */ return nskb; }
